While your properties hold significant equity, adding debt from HELOCs or a DSCR loan could strain your finances if STR performance fluctuates or costs rise.

People responded by explaining that residential mortgage lenders are looking for US-based customers, who have their residence, income and assets in the States.How do they view foreign debt?

What makes it tough in the beginning is your rental income is not established so you need to be able to handle the debt not using rental income. 

@Seth RolandLoans like bank statement loans or DSCR (Debt Service Coverage Ratio) loans could be great options.

For me I invest my SDIRA money in debt investments which typically are ordinary income when using w2 income and use my hard earned cash to buy properties. 

Before I give my answer I'm making the following assumptions- Your credit is decent, you have stabe income and make decent money; your debt to income ratio is relatively low. 

I would agree with Chris, I would not use debt to cover all costs and then hope to get a good pop on the sale to cover all the debt, payments and still have some in the end to make a profit to do it again.

@Shawn Nofziger I recommend using debt from the start even if you can self fund.

Only mortgages as debts which are covered by rents.

I wanted to restore it to the home I knew it once was and could be again!
