Mortgage Killer Accelerator

32 cycles, repeated for 50 years

Each cycle is a loop: do it, measure it, do it again. 16 of them are counted in the 150-house game plan. The other 16 are upside or protection and are left out of the numbers on purpose.

Combinations

Launch, ages 35 to 39 (7 cycles)

Build the savings machine and buy the first homes with ordinary loans.

Cycle 1 · Launch

Withholding reset to savings

  1. Fix the W-4 so no refund builds up
  2. Send the extra pay each month to the house fund
  3. Repeat every January and after any raise

Counted in the model. Uses: Stop over-withholding and send it to principal.

Risk: None beyond discipline.

Cycle 5 · Launch

House-hack ladder

  1. Buy a 2 to 4 unit home with an owner-occupied loan
  2. Live in one unit and rent the rest for the required year
  3. Move to the next one and keep the first as a rental

Not counted: upside or protection. Uses: House hack: rent a room, a unit or an ADU.

Risk: Owner-occupancy rules must be followed honestly.

Build, ages 40 to 59 (13 cycles)

One or two leveraged buys a year, then the first rehab-and-refinance deals.

Cycle 8 · Build

Buy, rent, hold

  1. Buy a modest house with 25% down on a 30-year loan
  2. Rent it only if the rent covers the payment, taxes and insurance by at least 1.1 times
  3. Repeat whenever cash above reserves allows

Counted in the model.

Risk: Thin cash flow per house at today's rates.

Cycle 9 · Build

Rehab and refinance (BRRRR)

  1. Buy a worn house for cash below its fixed-up value
  2. Repair and rent it
  3. Refinance at 75% of the new value and get most of the cash back
  4. Repeat with the same cash

Counted in the model.

Risk: Rehab overruns, low appraisals and slow refinances.

Cycle 10 · Build

Reserve ladder

  1. Hold about six months of rent per house in cash
  2. Grow the reserve with every purchase
  3. Never buy with reserve money

Counted in the model. Uses: Move idle savings above the emergency fund to principal.

Risk: Holding cash feels slow; it is what survives bad years.

Cycle 11 · Build

Yearly rent review

  1. Check market rent every renewal
  2. Renew good tenants at fair market rates
  3. Fix what drives turnover

Counted in the model.

Risk: Raising too fast causes vacancies.

Cycle 12 · Build

Turnover make-ready

  1. Standard paint, flooring and fixtures in every house
  2. Turn a vacant house in under two weeks
  3. Track days vacant

Not counted: upside or protection.

Risk: Contractor reliability.

Cycle 15 · Build

Same-payment refinance

  1. When rates fall well below a loan's rate, refinance with no cash out
  2. Keep paying the old payment
  3. The difference goes to principal

Not counted: upside or protection. Uses: Refinance lower, keep paying the old payment.

Risk: Closing costs; only when the drop is large.

Cycle 17 · Build

Assumable loans

  1. Look for homes with assumable low-rate loans
  2. Assume the loan and pay the seller's equity
  3. Keep the low rate

Not counted: upside or protection. Uses: Buyers: assume a seller's lower-rate FHA or VA loan.

Risk: Lender approval and large equity checks.

Cycle 19 · Build

Manager hand-off

  1. Self-manage the first houses to learn
  2. Hire a manager by about 20 houses
  3. Audit the manager every quarter

Counted in the model.

Risk: Bad managers are expensive; the model budgets 8% of rent.

Cycle 20 · Build

Lender ladder

  1. Use standard loans for the first ten financed properties
  2. Move to portfolio and rental-income loans after that
  3. Keep two or three lenders competing

Counted in the model.

Risk: Portfolio loans cost more and can have shorter terms.

Scale, ages 60 to 71 (4 cycles)

Four rehab deals a year plus leveraged buys, on portfolio loans after the first ten.

Cycle 21 · Scale

Like-kind exchange upgrade

  1. Sell a house that has gained a lot
  2. Exchange into two cheaper, higher-rent houses
  3. Defer the tax on the gain

Not counted: upside or protection. Uses: Sell a rental property and pay off the home.

Risk: Strict deadlines and rules; use a qualified intermediary.

Cycle 22 · Scale

Stress drill

  1. Every year, test the portfolio at rates 2 points higher and rents 10% lower
  2. If it fails, stop buying until it passes
  3. Pay down the weakest loans

Counted in the model.

Risk: Skipping it is how portfolios fail.

Cycle 23 · Scale

Prune and replace

  1. Sell the worst 3% to 5% of houses each year
  2. Replace them with better ones
  3. Keep the portfolio young

Not counted: upside or protection. Uses: Sell a rental property and pay off the home.

Risk: Selling costs 6% to 10%.

Cycle 24 · Scale

Rehab crew cycle

  1. Keep one trusted crew busy year-round
  2. Schedule rehabs back to back
  3. Four deals a year is the plan's pace

Counted in the model.

Risk: Losing the crew stalls the plan.

Kill the debt, ages 72 to 80 (4 cycles)

Stop buying. Every dollar of net rent goes to the highest-rate loan first.

Cycle 26 · Kill the debt

Paid-house snowball

  1. Each house that is paid off frees its payment
  2. That payment joins the next payoff
  3. The payoff speeds up every month

Counted in the model. Uses: Debt rollover: redirect every payment that ends.

Risk: None beyond discipline.

Cycle 27 · Kill the debt

Recast after big payments

  1. After a large principal payment, ask the lender to recast
  2. The required payment drops
  3. Cash flow and safety rise

Not counted: upside or protection. Uses: Lump sum from idle assets, then recast.

Risk: Not every lender recasts.

Harvest, ages 81 to 85 (4 cycles)

Debt-free. Net rent buys houses outright, for cash, every year.

Cycle 29 · Harvest

Cash-buy cycle

  1. Debt-free, let net rent build
  2. Buy the next house outright
  3. Repeat several times a year

Counted in the model.

Risk: Prices keep rising; cash buys get fewer per dollar.

Cycle 32 · Harvest

Family office hand-off

  1. Train a successor or a professional manager
  2. Write the operating manual
  3. Hand off gradually before 85

Not counted: upside or protection.

Risk: A portfolio this size needs a team.
