Market Analysis Framework

Score each market (0-100):

Market grades:

• 80-100: Aggressively acquire
• 60-79: Selectively acquire (cherry-pick deals)
• 40-59: Hold existing, don't acquire
• Below 40: Consider exit

Phase 2: Deal Sourcing

8 Deal Channels (Ranked by Quality)

1. Direct Mail — Targeted lists (absentee owners, tax delinquent, estate/probate). Response rate: 1-3%. Cost: $0.50-$2/piece
2. Driving for Dollars — Physical scouting for distressed properties. Free but time-intensive. Use DealMachine or similar to track
3. Wholesaler Network — Pre-negotiated deals at markup. Verify ARV independently. Quality varies wildly
4. MLS (Agent) — Listed properties. Most competitive. Look for: days on market >30, price reductions, motivated keywords
5. Auction — Foreclosure, tax lien, estate. Due diligence limited. Cash required. Discount: 20-40% typical
6. FSBO — For Sale By Owner. Direct negotiation, no agent commission baked in
7. Networking — REI meetups, BiggerPockets, local REIA chapters. Long-game relationship building
8. Online Marketplaces — Zillow, Redfin, Realtor.com, Roofstock, Auction.com

Deal Screening Checklist (5-Minute Filter)

□ Meets price range criteria
□ Rent-to-price ratio > 0.7% (or flip ARV margin > 30%)
□ No deal-breaker conditions
□ Neighborhood grade C+ or better
□ Verified comparable sales within 6 months
□ No major structural red flags from photos
□ Zoning allows intended use
□ Insurance obtainable (not in exclusion zone)

If ALL checked → proceed to full analysis. If ANY unchecked → pass or investigate.

  NOI = Annual Income - Annual Operating Expenses (excluding mortgage)
  GRM = Purchase Price / Annual Gross Rent
  DSCR = NOI / Annual Debt Service (lenders want > 1.25)
  50% Rule (screening): Expenses ≈ 50% of gross rent (excluding mortgage)

  = Total Selling:     $______

TOTAL INVESTMENT = Acquisition + Rehab + Holding + Selling

PROFIT = ARV - Total Investment
ROI = Profit / Cash Invested × 100

RULES:
  70% Rule: Max Offer = ARV × 0.70 - Repair Costs
  Minimum profit target: $25,000 or 15% of ARV

BRRRR Analysis

BUY:     Purchase price + closing costs
REHAB:   Renovation budget + contingency
RENT:    Market rent verification (3+ comps)
REFINANCE:
  After Repair Value (ARV):     $______
  Refinance LTV (75%):          $______
  New Loan Amount:              $______
  Cash Recovered:               New Loan - Original Loan Payoff
  Cash Left In Deal:            Total Invested - Cash Recovered
REPEAT:
  Cash-on-Cash = Annual Cash Flow / Cash Left In Deal
  Target: Infinite return (recover 100%+ of cash invested)

Stress Test (MANDATORY Before Buying)

Run every deal through these scenarios:

If ANY scenario = financial distress → don't buy or renegotiate terms.

Phase 5: Financing

Loan Type Decision Matrix

Creative Financing Strategies

1. Subject-To — Take over existing mortgage payments without formally assuming. Risk: due-on-sale clause
2. Seller Carryback — Seller acts as lender for portion. Combine with bank loan for lower down
3. Lease Option — Control property with option to buy. Lock price now, close later
4. Self-Directed IRA/401K — Use retirement funds for real estate. Complex rules, need custodian
5. Partnership/JV — One brings capital, other brings time/expertise. Define roles in operating agreement
6. Private Money — Borrow from individuals at agreed terms. More flexible than hard money

Refinance Decision Framework

Refinance when ALL true:

• New rate saves >0.5% AND payback period \x3C 3 years
• OR cash-out refinance recovers capital for next deal
• Sufficient equity (>25% after refi)
• Plan to hold property >3 more years
• No prepayment penalty or penalty \x3C savings

Maintenance Priority System

Phase 7: Tax Strategy

Real Estate Tax Benefits

1. Depreciation — Deduct property value (not land) over 27.5 years (residential) or 39 years (commercial)
   • Cost segregation study: accelerate depreciation on components (5, 7, 15 year)
   • Bonus depreciation: 40% in 2026 (declining annually)
2. Mortgage Interest — Fully deductible on investment properties
3. Operating Expenses — Property management, insurance, repairs, travel, education
4. 1031 Exchange — Defer capital gains by reinvesting in like-kind property
   • 45-day identification period, 180-day closing deadline
   • Must be equal or greater value and debt
5. Real Estate Professional Status — If qualified (750+ hrs, material participation), deduct losses against active income
6. Opportunity Zones — Tax benefits for investing in designated areas
7. Pass-Through Deduction (199A) — Up to 20% QBI deduction

Annual Tax Checklist

□ Track all income by property
□ Track all expenses by property (receipts!)
□ Calculate depreciation (include improvements)
□ Document mileage for property visits
□ Review 1031 exchange eligibility for any sales
□ Evaluate cost segregation for new purchases
□ Review RE Professional status hours log
□ Consult CPA before Dec 31 for year-end planning

    next_action: ""      # hold, refinance, sell, improve

Hold vs Sell Decision Framework

Sell when 2+ are true:

• Cash-on-cash return \x3C 5% AND no appreciation play
• Property requires >$20K deferred maintenance
• Market at cyclical peak (price-to-rent ratio stretched)
• Better use of equity elsewhere (opportunity cost)
• Management headaches disproportionate to returns
• Neighborhood in sustained decline
• 1031 exchange into superior asset available

Hold when:

• Cash flow positive with growing rents
• Below-market mortgage locked in
• Significant depreciation remaining
• Appreciation trend intact
• Low management burden
• Strong tenant in place

Scaling Strategy

Phase 9: Short-Term Rental (STR) Operations

STR Feasibility Analysis

REVENUE ESTIMATION
  Average Daily Rate (ADR): $______ (AirDNA, PriceLabs, comp search)
  Occupancy Rate: ______% (conservative: 65%, good: 75%, great: 85%)
  Monthly Revenue = ADR × 30 × Occupancy Rate

ADDITIONAL STR COSTS (vs long-term rental)
  Furnishing (one-time): $5K-$25K depending on size
  Cleaning (per turnover): $75-$200
  Supplies/amenities (monthly): $100-$300
  Channel management software: $50-$200/mo
  Dynamic pricing tool: $20-$100/mo
  Professional photos: $200-$500 (one-time)
  Higher insurance: +$500-$2K/year
  Higher utilities: +$200-$500/mo (you pay all)
  Licensing/permits: $0-$5K/year
  Occupancy/tourism tax: varies (8-15% of revenue)

NET = Revenue - All LTR Expenses - Additional STR Costs
Compare: STR Net vs LTR Net. Need >30% premium to justify extra work.

STR Listing Optimization

TITLE FORMULA: [Unique Feature] + [Location/View] + [Key Amenity]
  Example: "Lakefront Cabin w/ Hot Tub | 5 Min to Slopes | Sleeps 8"

PHOTOS (20+ required):
  1. Hero shot (best exterior or view)
  2. Living room (wide angle, lights on)
  3. Kitchen (clean, staged)
  4. Master bedroom
  5. Master bathroom
  6. Each additional bedroom
  7. Outdoor space / patio
  8. Amenities (hot tub, pool, game room)
  9. Neighborhood / attraction proximity
  10. Welcome touches (basket, guidebook)

DESCRIPTION STRUCTURE:
  Para 1: The experience (emotional, what makes it special)
  Para 2: The space (factual, beds/baths/capacity)
  Para 3: The location (distance to attractions, restaurants)
  Para 4: The amenities (bullet list)
  Para 5: Guest expectations (house rules, check-in)

PRICING STRATEGY:
  - Use dynamic pricing (PriceLabs, Beyond, Wheelhouse)
  - New listing: 20% below market for first 5 bookings (reviews)
  - Weekend premium: +20-40%
  - Event/seasonal premium: +50-200%
  - Last-minute discount: -15% within 3 days
  - Length-of-stay discount: 10% weekly, 20% monthly

Phase 11: Market Cycles & Timing

Real Estate Cycle Phases

EXPANSION → HYPER-SUPPLY → RECESSION → RECOVERY → EXPANSION...

EXPANSION (BUY)
  Signals: Rising rents, falling vacancy, new construction starting
  Strategy: Acquire aggressively, lock long-term financing

HYPER-SUPPLY (CAUTION)  
  Signals: Overbuilding, rising vacancy, rent growth slowing
  Strategy: Stop acquiring, focus on operations, build reserves

RECESSION (PREPARE)
  Signals: Rising vacancy, falling rents, distress sales emerging
  Strategy: Hold cash, hunt distressed deals, negotiate hard

RECOVERY (AGGRESSIVE BUY)
  Signals: Vacancy stabilizing, construction stopped, prices bottoming
  Strategy: Maximum acquisition mode — best deals of the cycle

Interest Rate Impact Rules

• Rate ↑ 1% = ~10% reduction in purchasing power
• Rate ↑ → prices soften (buying opportunity if cash flow still works)
• Rate ↓ → prices rise (refinance existing, sell flips)
• Always underwrite at current rates + 1% buffer
• ARMs: only if plan to sell/refi within fixed period

Quality Scoring (0-100)

Edge Cases

First-Time Buyer

• Start with house hack (FHA 3.5% down, live in one unit)
• Build reserves before buying investment property
• Get pre-approved, then find deals (not reverse)

Remote Investing

• Visit market first (fly once, walk neighborhoods)
• Build team BEFORE buying: agent, PM, contractor, inspector
• Never rely solely on photos — video walkthroughs minimum

Inherited Property

• Get appraisal immediately (stepped-up basis = date of death value)
• Evaluate: sell, rent, or 1031 exchange
• Clear title issues ASAP (probate timeline varies)

Rising Rate Environment

• Focus on cash flow over appreciation
• Seller financing and assumable mortgages = gold
• Negotiate price reductions (fewer buyers = leverage)
• Avoid ARMs unless very short hold period

Tenant Disputes

• Document everything in writing
• Follow local eviction procedures EXACTLY
• Offer cash-for-keys before formal eviction (often cheaper)
• Never self-help evict (illegal everywhere)

Natural Disaster / Insurance

• Get proper coverage BEFORE closing (flood, earthquake, wind separate)
• Document property condition with photos/video
• Keep separate reserve for insurance deductibles
• Review policy annually — don't be underinsured
