I agree with the others here that say you need to have some skin in the game, if you are going to live there yourself, get an FHA loan rather than owner financing, you can get a 3.5% down loan, personally I do not love these as they require  PMI which is an additional expense, and you also need  bring additional funds for closing at least for taxes, title, attorney and transfer fees . borrowing from anyone else for the down payment, to include a personal loan from the bank is not a good idea, those again will be higher int. rate.

This includes a hotel, winery, mobile home park, parking garage, debt fund, etc.

Maintain - includes taxes and insurance?

I have seen it backfire when companies attempt to get posts removed, including with legal threats.

Do you include specific clauses in each of your subject to deals spelling out exactly how insurance on the property will be handled?
