I'm still working on finishing my house.
My DH and I started flipping houses in 2013 when the bottom fell out of the company we worked for. Bought the first flip for $65K cash, put $40K into it and sold it 1 yr and 1 wk later for asking price: $177K. I sold it so we saved 3% on the Realtors commission. The only thing we hired out was a plumber to install the new on demand DHW/boiler system and all the BB registers and my electricians to upgrade the service entrance cable to the load panel.
That was it.
I was hooked.
We bought 3 more highly distressed properties over the next 3 years and moved from house to house. (Our house took over a year to sell because it was bordered on three sides by a cemetery.) Moving once a year got old so we started looking for a house for us and found it within 2 weeks of deciding we'd had enough. I've been working on the lion's share of it myself over the last 5 years because my DH developed early onset Alzheimer's and can't do anything any longer. Signs were showing on the second flip.
So I have to finish installing the cultured stone on the front of the garage and build the column bases on the front porch and put it there too. Build the seasonal room on the deck, tear off the roof on the back of the house and likely repair a popped truss and reroof that side, dig out the pond and build that, build a shelter for the lawn tractor, install a stacked stone retaining wall around the garage, move the electric fence and gate for the chicken's pen, install a loose lay flagstone path from the house to the coop and run, build the master bathroom, remodel the other bathroom, finish the spare room and master bedroom, then reside/reroof the shed and I'm finally done!!!
The slow finish on our house was compounded by me finishing the house that I grew up in so it could be sold after my Dad died then renovating a house for my mother. It's also very hard to take care of someone with AD when they were your partner, you still have to work and you have no one to help you with it. It's not so much the time as the toll it takes on your mind and spirit.
