Right now, you have a property with a great equity position, solid cash flow, and cheap debt (interest rate is low). 

The going rate varies by market, but some agents will do it for free in exchange for any unrepresented buyer leads, while others may charge $50-$100 depending on the demand in your area.Wishing you and your wife all the best—exciting times ahead!

@Robert BriggsSince a cash-out refi and HELOC aren’t viable options in Texas, and personal loans have high interest rates, consider a few alternatives.

Industrial vacancy rates for your size building are ridiculously low. 

Do the calculations factor in default rates?

LTV can reach 70~80% even the cap rate is only 4.0%.

Quote from @Tobias Joneses: I'm looking at the numbers and with interest rates seeking 6.5.

@Andrew Self I would like to think that my company is the best and offers the lowest rates and closing costs, but perhaps I am bias.

@Ellis Moyewe really don't know a lot about this situation since there aren't many details in your post... but i don't think this makes any sense for anyone involved here...if it's a flip that's not selling, refinancing may not solve your problem and allow you to pay back the HML in fulland typically a sub to buyer wants a low interest rate... and if you refinance now you won't be getting a low interest rate, you'll just be getting whatever the market offers.and finally.... the vast majority of loans are NOT assumable. 

The big difference is DSCR loans are higher interest rates.
