Investment strategies

House hacking is one move. You buy a place with more than one unit, like a duplex, or a house with spare rooms. You live in one part. You rent out the rest. Your tenants pay most of your housing cost, and sometimes all of it.

Rent used to leave your account every month and never come back. Now part of your home earns money while you sleep in it.

Here is why it costs the least cash to start. When you live in the property, the lender treats it as your home. A home you live in gets the low first-timer down payment, often 3% to 5%. An investor who will not live there pays 20% to 25% down.

Look at the gap. On a $200,000 place, an investor puts down 20%, that is $40,000 in cash. Live in it yourself and a first-timer might put down 5%, that is $10,000. Same building, one quarter of the cash, because you sleep there.

You still carry a mortgage like any buyer. If your down payment is under 20%, you also pay PMI each month. On the low-down FHA loans many first-timers use, that charge stays for the life of the loan unless you refinance later. Plan for it as part of the deal.

Renting the other side makes you a landlord. That is a real part-time job. You screen who moves in. You fix what breaks. You keep a repairs fund so a broken water heater is an errand and never a crisis. You plan for vacancy, the weeks a unit sits empty and pays you nothing.

House hacking adds one thing a normal rental does not have. You live next to your tenant. That is close. Put every rule in writing before anyone moves in. Rent amount, due date, quiet hours, who handles the yard, how repairs get reported.

Here is the shape of a good house hack. If the rent from the other side covers most of your monthly loan payment, you live close to free. The same paycheck saves far more. Every month you live cheap, more cash piles up for the next move.

Lenders usually ask you to live in the home for about a year. After that, you can move out, rent your old side too, and both sides pay you. Your house hack has quietly become a full rental. Then you can do it again with the next place.

Flipping is buying a home that needs work, fixing it, and selling it for more than you put in. Buy low. Fix smart. Sell.

Here is the part most TV shows leave out. The profit is locked in the day you buy, never the day you sell. If you pay too much going in, no paint, no new kitchen, and no clever staging can rescue the deal. Good flippers make their money at the buy price.

Before you buy anything, you need one number cold and clear. The ARV, or after-repair value, is what the fixed-up home will really sell for on that street. You get it by looking at homes just like yours. Same size, same area, already fixed up, sold in the last few months. Be brutal with that number and round it down.

Do not lean on the market rising to save you. A home gaining value over time is called appreciation, and it is never promised. Price the deal on what the home is worth today, after it is fixed.

Everything goes right.

Total in is every dollar that leaves your pocket. The buy, the work, months of loan payments, taxes, and the fees to sell.

Now the same home with three normal setbacks. The walls hide more than the plan expected. The work runs long. The market cools a bit.

Read that slowly. The rehab went from $35,000 to $50,000 because of what was behind the walls. Four extra months of payments and taxes added $6,000. The market softened, so it sold at $182,000. Three ordinary setbacks turned a $22,000 profit into a $12,000 loss. That is a $34,000 swing on one house, and nothing reckless happened.

Learn the four ways flips die, and you will pass on the deals that would have hurt you.

• Surprises behind the walls. Old wiring, bad pipes, a soft roof, water damage. Your rehab number is a guess until the walls come open, so pad it and get real quotes.
• Timeline slip. Every month you hold the home, you pay the loan, the taxes, the insurance, and the lights. Three extra months quietly eats thousands.
• Over-improving for the street. A high-end kitchen on a modest block does not sell for high-end money. Fix to match the neighborhood, never above it.
• Falling for the after picture. The finished home in your head is always worth more than the one that actually lists. Price the boring, likely sale.

A flip is a job. For months you manage crews, chase quotes, pull permits, and make a dozen calls a week while the payments run. It pays well when a deal goes right. It also stops paying the day you stop working. Sell the home, and the income ends until you find and fund the next one.

BRRRR is a plan hiding in five letters. Buy, Rehab, Rent, Refinance, Repeat.

• Buy. You buy a rough, cheap house with cash or a short loan.
• Rehab. You fix it up. New floors, fresh paint, a kitchen that works.
• Rent. You put a tenant in and become a landlord.
• Refinance. You refinance, which means you get a new loan on the higher, fixed-up value and pull most of your cash back out.
• Repeat. You take that cash and go buy the next one.

With a plain rental, your down payment is stuck. You put $30,000 down and it sits in the walls for years. BRRRR breaks that. You buy rough and cheap, then fix the house so it is worth more. That fix builds equity, the part of the home you truly own. A bank writes a new loan against the bigger value and hands your cash back.

Walk one cycle slow. These are teaching numbers, not a promise on any real house. Say you buy a rough house for $100,000. You put $30,000 of work into it. That is $130,000 tied up in the deal. Fixed up and rented, the house is now worth $160,000.

Now the refinance. A bank will lend against the finished house, often around 75% of its value. 75% of $160,000 is $120,000. The bank writes you a new loan for that $120,000 and pays off your short loan.

Read the math straight. You put in $130,000. You pulled about $120,000 back out. About $10,000 stays parked in the deal. You keep the house, a tenant pays you rent every month, and that $120,000 becomes the seed for the next one.

That refinance number is a promise the market never made. If appreciation stalls and values drop, or rates rise, the bank hands back less than you hoped. Your cash stays stuck in the walls. The plan does not fail loudly. It just freezes, with your money inside.

Watch the cash flow too. The new loan is bigger than a plain rental loan, so the payment is bigger and the money left over each month is thin. Add a slow stretch of vacancy and thin can turn negative.

Every step here leans on a skill from an earlier page. Finding a deal cheap. Holding the line on the fix budget. Landlording. Reading a loan before you sign. BRRRR stacks four skills you had to learn one at a time. That is why it comes last.

Three things have to be true before you touch it.

• You have done a deal or two already, a first rental or a flip.
• You keep 6 months of reserves in cash.
• You can survive the refinance never happening. If the cash stays stuck for a year, your life is fine.

If any one of those is shaky, come back when it is solid. There is no prize for rushing.
