Now the question:Option 1: Should I pay for repairs to my basement out of pocket, and use the equity to fund an entirely new second investment property?

Not a rental first and then your primary.)You can defer the taxes by reinvesting the entire net sales proceeds (including mortgage payoff amounts) or more in a new rental, this does not apply to primary homes.

A good handyman and possibly a realtor for future leases/other items and you should be good.

If you connect with a elderly homeowner who wants to learn more, if possible, make sure they have a younger/responsible adult that they know and trust to avoid bad optics.   

If the IRS labels you a "developer", which seems like a real possibility given your investment model, then your properties switch from "capital asset" to "inventory".

If the goal is to "just get it done," and there are residential realtors involved that think closing in 21 days matters (in the SFR world, it does), then this honestly may be the best route.A true commercial loan will have an interest rate on-par with a 30YF primary residence SFR rate, but rather than being a 30YF, it'll be fixed for 5-7 years, and then you have to pay the mortgage off entirely, most commonly by refinancing. 30 year amortization may still be in play.
