I would still do due diligence such as whole property inspection, lead inspection (depending on when the property was built), appraisal, etc. 

@Stefano Vrolijk it all depends on your credit history, whether you have an SSN/ ITIN and how much you can put down.

Short answer: Yes, laundromats can be profitable, but profitability depends on a few factors.

Depending on your goals and how you are buying your properties you may notice that certain areas are difficult to cash flow in NH depending on your strategy and what type(s) of properties you are looking at. 

Depending on the salaries of the new jobs they may also price out the local residents on new home sales which would further drive up the price.

I would only do it if it was an absolute no brainer of a deal as if it goes south then you not only hurt yourself on that deal but also the property that you took the heloc out of.This also depends as if your current LTV is 30% and want to go to 50% is different than going from 50% to 80%.

All of this depends on your market having demand, of course. 

It all depends.

Of course it all depends on pricing and what your target demo is.

Is it dependent on how you get funding?
