Another option that requires more legwork is to call the servicer/ producer of the inverter.

Homewrite is seems like it could be a good option.

Do you limit the term to 6 months to begin with, or 30 days minimum stay and negotiate an option later on?

You won’t find many seller-financing deals here, so if you're looking to scale quickly, your next best option is the BRRRR method—using cash or hard money to acquire properties and DSCR loans to refinance into. 

I think the first step would be to contact a lender and figure out our best options moving forward.

I Hope with this new perspective perhaps some new options have opened up for you! 

One option is to buy the home and pay them out in installments rather than taking out a bank loan right away.

@Max Bellino For smaller properties like your 2–4 unit multifamily buildings, an online cost segregation study is a quicker and more cost-effective option, providing sufficient accuracy for straightforward properties.

I’ve heard of a few different options but would love to hear your experiences, especially if you've used gap funding on flips, new construction, or commercial projects.

Seems to me my options are...SELL - If I were to put it on the market I think I could reasonably get $2.8M - $3M, but at a 2.9M sale price my return on my initial investment is only 38%, or 7.6% a year over the 5 years.
