Hello. i'm under contract to purchase a duplex which I will convert to an STR. 

They understand that it would have to be at a discount to the amount owed and would need to make sense for me.There is roughly $360K in unpaid principle @4.00% and 311 monthly payments remaining. 

Two, has anyone used FutureStay.com?

I have used Yellow letter HQ and I have only good words to say about them.

He had no losses and lead me to believe I would get my deposit back initially.

So, a tenant caused extension damage to my property.

Say we buy a property for $1 million, but we structure it so it's 0% down but a bank/note buyer is in place at closing to buy the note from the seller at 80% value so they walk away with 800k in cash. 

You could try getting a HELOC with your primary and using this money as short term funds to acquire rentals that need a light-medium renovation using 100% purchase/rehab hard money and just using the HELOC to pay points and holding costs.

I’m looking to purchase a duplex in Charlotte, with one unit being turn-key and the other in need of repairs.

Have you considered using long-term rental loans to finance your properties?
