Rent to Own Or Co-sign??

[Rick Wood]

Just putting this out there for some feedback and wisdom. I have a couple of investments and am about to jump into a Short term rental while still being a w-2 employee. My son (age 24) however, is an independant contractor / self employed and is trying to buy a house. He is making decent $, has a good 2.5 years of solid rental history. He is very good about deductions on tax returns so his income looks negligible and of course banks wont talk to him about loans. Wondering if you have advice on me just being the bank, where I purchase a house and structure a rent to own with him and have him build up a 30% cash down payment and some equity and then me sell the house to him at a locked in price. I dont get much out of it as an investor except getting my son in a house vs staying in the rental market. This could also hurt my debt ratios if I go to borrow on another investment somewhere like my plans for the STR. Another option is to co-sign but that has the same impact on my credit and responsibility to the bank. Seems like there are a lot of individuals in this boat - especially in my sons line of work - which is lighting and tech for special events and music tours. Thank you in advance for your thoughts!
