My mortgage broker says it should be fine but I'm not 100% sure.  

Straight mortgage 30 year but since I knew I wasn’t going to keep it I negotiated a higher interest rate for less money down and buyer credits at the table which saved $1000s How did you add value to the deal?

Complexity of course makes a difference, but an old mortgage or some other blip on title no one would contest isn’t a painful process usually. 

Apply mortgage.

I own a home in Beavercreek and I'll be selling it when I have to move in a half a year because the rents would barely cover the mortgage/taxes/insurance.

It does need a new roof, repaving the parking lot and general repairs.Currently I own one condo worth about 100k free and clearPersonal house has 170k mortgage and I have about 20k in personal debt.What do you guys think?   

No mortgage on the house.

I also have a first mortgage of 100k. 

You borrow the $20k downpayment plus $5k in closing costs and $5k in rehab costs from your HELOC also at 6% (note $5k in rehab costs in nothing so the house better be newer and in great shape).Let's say you rent the property out for $1000/month and using the 50% rule you have $500 in expenses each month.Your mortgage payment will be $480/month.

Do you sell your mortgages?
