In late 2017 my brother was offered to purchase a house from his wife's family for them to live in for about half of what it was appraised for. He had been renting for a few years so decided to go ahead and purchase it and have the house completely renovated since it was pretty outdated and old. Issue was that his credit was not that great at the time so my dad offered to help him out and pretty much purchase it and my brother would be paying the mortgage, taxes and any other fees associated with it just as if he had the loan in his name. His plans were to work on his credit and then take it off my dad's hands as soon as he was able to. As of now the home is almost complete, it has been completely renovated from inside and out. My brother has paid for everything out of pocket and sometime this year he would like to take the loan off my dad and put it under his name.
Some questions I have are is it possible for my brother to purchase the home from my dad for more than what it was sold for without having to pay capital gains? Example is my dad purchased the home for $40K and my brother put $25K into renovating it can he purchase it for $65K if the house appraises for more and avoid capital gains? Also when my dad go's to do his income taxes should he be including it as investment property? Any way to recoup some of the money my brother has put into the home? It's basically a new house, everything has been redone. All electrical, plumbing, HVAC, spray foam insulation, energy efficient windows, etc...He does have all the invoices and receipts from the contractor doing all the work. They do plan on meeting with a CPA about it but just wanted to get them some info to be a little better prepared for when they meet. Any advice would be much appreciated.
