I would like to know more about ways to use OPM  The only way to determine if the home is going to cost you a lot down the road is by determining the age of the mechanical systems & if the structure of the home is sound. 

RE investors do this type of structure all the time (though most don't house hack).

With a few tweaks to the management structure, and with new leadership, I figure we can greatly increase the revenue.

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.  

Detached: A separate structure like a tiny house, guest house, or mother in-law suite in the backyard.2.

Quote from @Gregory Banks: I would hire a structural engineer. $1,000 inspection could save you tens of thousands.

If you’re set on condos, ensure you’re targeting areas with strong rental demand and minimal HOA restrictions.Regarding an LLC, it’s great for liability protection, but it won’t necessarily give you tax benefits unless structured strategically.

When looking to structure a deal like this, look for a dated property in working condition.

Here is some key information:Property recently hit the market and has 2 cash offers alreadyThe seller provided a pre-inspection report, which I shared with 2 different lenders, both think it may fail conventional financing due to potential structural and electrical issues (realtor thinks it could pass conventional)Seller has 100% equity but is behind on other payments (not sure of the urgency money is needed)This is my first attempt at an “investment” property so I’m new to thisI see 3 optionsMove forward with an offer using conventional loan pre-qualification-Not as attractive of an offer to the seller-Possibility that appraiser calls out structural/electrical issues that need to be fixed before closing, effectively causing financing to fail- Best terms and fewest loan fees for meUse a rehab style loan such as ChoiceRenovation-Even less attractive than a conventional offer to seller, but less risk of failed financing if appraiser calls out issues-Slightly worse fees and interest rates compared to conventional-Lenders tell me possibly up to 60-90 days closing in some cases, with red-tape for contractor requirements and draw schedules (sounds like the most hoops to jump through during rehab)Use a hard money lender-Most attractive loan option I can give to seller so I can compete-Much higher fees and interest rate for me-need to refinance into a conventional at the end of rehab (not familiar with seasoning periods but I think this is a factor as well)Which option would you do?

There's a very specific ways to calculate FHA income, and it will be highly dependent on how the deal and your ownership is structured.
