Short term rentals usually price best 65-70% loan to value but if the cash flow is very strong to support a higher rate up to 80% is still possible these days (not common though).Best of luck.

It is going to be a VARIABLE rate and is typically higher than a cash out refinance. 

When tenants are so far behind, there's a good chance they can't afford market rates.

I am currently looking at buying a new construction home as a long term rental property. sales price $214000. first my lender told me I can do 0 down. and I am really excited about this deal. but later he told me that am not qualified for 0 down because of my income. the other option is that I can do fha with 3.5% down, 6.125% interest rate. cash to close is $14000. my monthly payment is around $1575-$1590.it can at least rent for $1700 as a long term rental property.

I have no idea about occupancy rates, management fees etc.

Just trying to figure out our options here, would love to keep the interest rate if possible for obvious reasons.

I might start by calling  my insurance agent and asking how this will affect my culpability, not to mention rates.

I would bet good money that they are paying below market rates.In case you missed it: get rid of them.Spruce the property up, study the market to determine a fair market rate, and find a renter that is willing to pay the market rate, pay the deposit, and abide by your agreement.Not everyone is cut out to be a good landlord.

We use cheap charcoal ones and budget for annual replacements.

Here's a bit more in detail about how rates are calculated for DSCR loans:1.
