My complicated situation aside I just wanted to answer questions 2 and 3 from your original post, you can split after building an ADU.

@Zachary Bellinghausen someone close to central FL who is an expert on Solo401k and real estate is Adam Bergman, IRA Financial Group, tax attorney and owner of company.

Then you run in to financial trouble, decide you hate the other buyers, want to leave the state, whatever.

I think (emphasis on think) I have found a deal for me but here is my situation: I am a recent college grad with no 2 year income (just yet) and I came across this property inHamilton, NJ, in which i need between 100k - 144k after all costs (rehab, closing, 20% down payment) I do not have this money as a 22 year old, so I naturally wanted to get an FHA loan but the problem is, its a quadplex that has all units occupied, so i cant really live here because there would be no space, unless there is a way around this.

For those of you who have been divorced, you should know that a judge can obligate you to pay child support, alimony, college tuition, private school tuition, mortgages etc...IS IT ILLEGAL for a landlord to ask for the finalized divorce agreement to see what potential FINANCIAL OBLIGATIONS a tenant is/could be responsible for that would affect his/her ability to pay the rent at a new residence?

God bless him and help him to get out of that situation

House hacking makes your tax situation more complex.You purchased a property that is treated as both an investment property and a personal residence.

I've had situations where we contracted with the homeowner the same day we met and there are some situations where takes  years. 

Patty's Day parade, this home is perfectly situated.

But, if my rent isn’t high enough to pay the mortgage and I’m paying out of pocket, is this a situation I should fix and flip the house?
