HI Lei
Welcome to the world of creative real estate at CashFlowDepot
What’s the house worth?
If the house is worth $185k, in good condition and he’s not motivated to sell fast, I honestly don’t see an opportunity here.
$50,000 down payment is not attractive enough financing to get involved.
Is he willing to sell for $135,000 ($50,000 down + pay off $85k Helco)? If so, you could get an option on the property for $135,000 then do a highest bidder sale. You’d sell to the highest bidder over $135,000. Your profit would be the difference between the $135k and what you can sell it for.
But if he wants $185k, it is not a good opportunity unless the house is worth a whole lot more.
rents are low and taxes are very high.
