Currently we are seeing STR owners posting for sale due to reduction in prices they can get per night and the vacancy rate increasing. 

The property itself should bring in revenue ( even if you choose not to live in one side) and generally a bank will accept a portion of that rental income into the calculation. 

From an email I received from FF:New year, new rental goals! There’s never been a better time to step into the booming mid-term rental market. Since you’ve shown interest in listing your property with Furnished Finder...

BUT I have also heard that it could trigger a due on sales clause, bringing the note fully due at any moment.

Every month, I collect a payment from Don, use a portion of his payment for my payment to Chase and keep the difference.

Almost every reputable lender is going to have a draw process for any lender funded rehab portion. 

Since part of your property is a rental, I believe a portion of your mortgage interest should be a tax deduction unlike your other debt.

This makes targeting distressed sellers, such as those in pre-foreclosure, or those with ballooning debt that was taken out in 2020-2021 when the interest rate was 7.37x lower (8/09/2020 the 10-year treasury was .56%, 1/15/2024 the 10-year treasury is 4.69%) making it very difficult for those that underwrote the property in 2020 to have predicted refinancing at these rates and likely a sale is their only option.

However, these properties generally have a lot of land improvements that qualify as well as certain portions of electrical, mechanical and plumbing that can qualify.

I'd be happy to assist with the financing portion (if you are considering here in HI).
