That you JV with Real Estate Investors to remove capital hurdles to make "deals" happen. 

Confirm with the solar company if the loan is transferable and review terms carefully—it’s a potential hurdle with lenders or resale.A DSCR (Debt Service Coverage Ratio) loan might be an option since you’re focused on rental income.

I think the 2 biggest hurdles are finding the right team to do the work, given you won't be there to monitor it 1st hand.

pretty small hurdle to have a good win as a private lender just get paid as agreed.now equity participation loans those can spin the needle pretty well ..

Quote from @John Williams: I recently bought a home that has an attached dwelling unit where Im planning to move in and rent out the main unit.

After 20 years in the investing game, plus working as an investor-friendly agent, I’ve learned that hesitation can feel like a big hurdle but often ends up being the push you need once you break through it.I’m personally based in San Diego, California, and licensed here, but I’ve also looked into projects across the country with folks who sought better cash flow.

For the main house, I'd get a washer and drier. 

I'm mainly looking for duplex, triplex or quadplex.  

That might be the biggest hurdle - but otherwise, I'd check out "DSCR Loans" which are the perfect option for people like you looking to buy rental properties w/o W2 or DTIWe don't own any other properties other than the investment property we just purchased.

Incorporating a washer-dryer hookup in the main house could be advantageous.This addition not only increases the convenience for potential renters but also adds value to the property itself.
