Aside from the cash-refinance cost itself)3) Does this mean the new mortgage (30-year conventional for the apartments) be based on the $1.8M with new interest rate (at the time), etc.?

I have a property that is dadu ready I have a heloc for 227,000 I want to build a dadu with the heloc money but I'm sure the cost is more than my heloc how do I get the rest of the money to finish the build so I could refi after to pay the heloc back could I get a construction loan for 100,000 to help finish the dadu?

Quote from @Henry T.: What?

Since the loan is at a low interest rate we do not want to refinance into our names and her parents are okay not refinancing as well.Thanks,Zack

@Alex Ng I think Birmingham is a great place to invest because of the cheaper prices and low taxes.

Some details on the deal below:Mortgage rate on the property: 3%Monthly mortgage payment: $1200Amount owed on mortgage: $230KCurrent property value: $370KEquity: $140KDue to the low mortgage payment and high rent potential in this neighborhood I would like to assume this loan and rent this property out as a long term rental. 

During that time they supposedly found a leak which was beyond the scope of the maintenance  and i had to pay a plumber to come in saturday morning while the guests were there. thats on top of the "deep clean" which cost $300 and was somehow done in a couple of hours. 

@Terri-Leigh H.can you breakdown what your costs are to furnish each bed and additional furniture, furnishings cost are for a 5 bed property. 35k seems high compared to what we have encountered.

The obvious play would be for the low purchase price/cash flow. 

Build mobile home on the vacant lot I understand the cost involved for rehab the existing house.
