Ran out of money for the fourth one and did not see it coming
This is the ceiling I keep talking about and I finally hit it with numbers attached, so here they are.
Started with 140k of my own cash 26 months ago. Plan was four single family rentals in two years, refinancing each one to fund the next.
House one: all in 168k, appraised 218k, refi at 75% gave 163,500, netted 22k back of 44k in. So 22k stranded. House two: all in 152k, appraised 189k, refi at 70% because the lender changed their cash-out terms mid deal, netted 15k of 41k in. 26k stranded. House three: all in 181k, appraised 226k, rehab ran 11k over, netted 24k of 53k in. 29k stranded.
So three houses, all rented, all cash flowing between 210 and 385 a month. That part is fine and I'd do it again.
What I did wrong was arithmetic. I built the plan on getting roughly 85 to 90% of my cash back each time because that's what the numbers looked like on deals people were describing a few years ago. I got 50%, 37% and 45%. After three deals my 140k had become 31k of liquid cash and about 77k of equity I can't touch without another refi and more debt service.
House four was under contract at 138k with a 43k scope. I had 31k. I tried to get a partner in for the rehab money for five weeks, couldn't paper it in a way that either of us liked, and ended up assigning the contract for 6k after eating 11 weeks of my own time and about 1,900 in earnest and inspection costs. Net positive on paper. It felt like a wall.
What I'd do differently: plan the capital schedule at 55% recovery per deal and see how many deals that actually buys, which in my case is two, not four. And hold a separate rehab reserve that is not allowed to be part of the next down payment, because the 11k overrun on house three is what actually emptied the account.
