However, i've spoken to some folks who think that the agent and their affiliated offices make a huge difference in finding tenants. 

Customer service is spotty, at best and dependent on which office/consultant you're working with. 

The top floor is a master suite. 2nd floor has 2 BR, office, shared bath, and laundry.

You're going to need a Loan Officer or Broker who is familiar with investor type loans.

Go to your local government planning office and ask them.

HI All - I'm considering a post office purchase.

But I also have a very demanding W2 (left the house 12hr ago and still haven't left the office). 

I'll second what Andrew said, We use Propelio in our office to make sure that what you as a borrower see is achievable before you spend money on an appraisal.

I am not longer motivated to be a loan officer in an office from 9-6.

Volatility and risk in the product type coupled with an economic slowdown... investors just aren't and won't be looking to place capital in the retail sector when other areas like multifamily and office remain hot.
