@Tim Delaney is an investor in the Buffalo market and shares many of your views on its long term potential!

Was that purchase money, rate and term refi, or cash out refi?

I think it would be better just to stay on good terms and let him know you will contact him when you are ready to sell.

This creates a market for both short-term and long-term rental properties.Affordable housing, Compared to cities like New York, Washington D.C., or Boston, Philadelphia offers relatively affordable rent, or section 8 tenants, especially those who are relocating from more expensive areas. 

We have a home that we are almost done remodeling that we would like to try the mid term strategy to increase our cash flow vs long term.

If you're goal is a long term hold, you're almost certainly going to do well even with a market rate deal in any of those states.

Will you use the HELOC as a short-term bridge, or plan to hold it longer?

@Rebecca GonaBigger Pockets is a great place to find a tax accountant that specializes in short-term rentals. 

Finally, double-check local demand and rent trends in the area to ensure the pro forma income is achievable.I’ve worked on several mobile home park deals as a broker and am currently helping a few clients sell their parks, so I know how important it is to ensure the numbers make sense both now and in the long term.

It seems like the tenant is being respectful, following the rules, and is not being a problem so I think that is what you would tell any other tenants who ask, as long as you have seen the card.
