While the co-signers add some security, the family’s newness to the U.S. and uncertain job situation make them a higher risk overall. 

We are now suing them in TX small claims court as the security deposit was not enough to cover the 2 - 3 months rent after they trashed the house. 

Even large and small businesses with intangible residual services like TV, internet, security, pest control or the local contractor with remodels in process could fall behind on payments revenue contract. 

My strategy would then be to lease at least two of the renovated units, increasing occupancy to 90%, which could improve the chances of securing favorable terms for refinancing.I haven't pitched it to the seller yet.

Securing financing upfront is paramount.

ps one investor one llc then there is no securities issues thats a benefit /  but now you have 20 companies to manage 20 sets of books 20 tax returns etc. 

Loan interest is deductible based on the use of the loan, not the asset securing the loan. 

Private lenders or even creating a small syndicate with a group of investors might also be worth exploring, especially since you can point to your uncle’s track record and your own experience managing rentals as a selling point.If timing is tight, you could look into a bridge loan to secure the property while figuring out a more permanent solution.

For example, I have a main account that is for my holding company, sub-accounts for each property, and sub-sub accounts for security deposits and things like CapEx for each property.
