Keep in mind that landlords in expensive markets aren't making an profit (cash-flow) on rent.

We aren't permitted to charge tenants utilities unless they're separately metered in Delaware

It can get really sticky, cause frustration and ruin a friendship if expectations aren't set up front.

Expensive and desirable aren't synonymous.

They aren't too concerned with the type of transaction (traditional homebuyer/seller or investment).

Any of the online auction portals aren't really doing what you think.

Based on personal experience, I would add assuring the lender is specifically authorized to perform an on-sight property inspection, at the lender's discretion / convenience. 

We aren't even implementing what we learned because we are too busy dealing with a personal issue and haven't been able to travel much for the last couple of years.

@Jaycee Greene I’ve contacted big banks small local banks and I haven’t quite tried credit unions although I have 2 credit unions for which I have accounts (but my experience is that they aren’t offering that much better terms).

Economics are powerful until they aren't.
