@Mashal Choudhry - Buy, Rehab, Rent out the property, Refinance (cash out), Repeat (buy a new home).
The theory is that if you bought a home for $200k with a $160k loan, and rehab'd the property, the value is now $250k. Then you do a cash out refinance and get 75%-80% loan to value on $250k, so a new loan of $200,000. The new loan of $200k pays off your old loan of $160k and you get the proceeds (minus closing costs) and you take that money and reinvest into new homes.
This method was amazing the past decade. But, it is getting more difficult right now.
1) Values are not increasing at the same levels. That helped a lot of investors out, when they rehabbed the home gained value but the market also jumped by 10% in that year so it made their values grow faster
2) Cash out refinances on conventional loans got more expensive and restrictive. 75% max loan to value on a rental property cash out refi.
3) Rates are up, which is not a show stopper but it makes things more challenging to cash flow.
BRRRR is still an option, but I think investors need to be more dialed in then ever.
