What is your process for underwriting a rental by adding an ADU (addition or division)?

Although this is unique in that its such a highly visible marketing effort. 

Lease Options: Structure a lease option for the property you're flipping, allowing you to control the property while securing financing through the lease payments.By combining these strategies, you can create a unique financing plan tailored to your specific project and financial situation.

I understand that everyone has unique goals, and responses will vary depending on those objectives.

Megan Luckily the math part isnt too high level just addition, subtraction, some mulitplication and division but we as a community can all help you through it.Leave the complicated math for the wall street quantative analysts and derivative traders.

If you can find smaller local banks in the market you pick they may have more unique products that they keep on their balance sheet or try and do the 5% down conventional on a 4-unit  FHA's self-sufficiency test applies to both 3 and 4-unit properties.

Analyze deals, build your network, and educate yourself constantly.If you have access to unique resources (like a VA loan, FHA Loan, or 401K), use them to your advantage!

With platforms like Airbnb or Hipcamp, you can attract travelers looking for unique stays.
