For all the commercial experts, how would you recommend I proceed in trying to secure financing this property? 

-Check and see if there is an easement on an adjacent property for a future driveway access to your landlocked property-If there is not, ask your neighbors nicely if you can add a driveway access to your property on theirs-Try to sell the land to an adjacent owner

However, if the attic is accessible on its own and is set up for heat, then it should be able to be counted as a 3rd bedroom. 

So going from residential to commercial or long term to short term rentals is perfectly fine.

When they're selling for $170,000 and renting for 1600/month, they can approach too-good-to-be-true.I do think the stadium will generate more commercial investment to the area, but I'd have to ponder more how that would play into appreciation/rent/demographic changes.

@Ann Bellamy do you know of any that focus, or at least touch on, commercial outside of multis/apartments?  

I'm interested in flips, mfh, and later down the road...commercial!

When someone posts it stays on here so one time I was in an eviction forum responding about the process and another about Veteran rentals.I have probably gotten hundreds of calls over the years for that and I had to explain I am not focused on that.So really I mainly post about commercial real estate as that is my daily life.

What fees are associated with assuming a commercial mortgage and how long does the process typically take?

Commercial?
