Wife wants me to pick up a salt lick from the store.

It's nothing like fancy pants hanging around kitchen stores picking out just the right cabinet door and handle pulls.

Heck, find all of the listings in your office, and pick the best ones and then reach out to the agents.Ask top agents if they could refer you to any buyers/sellers/renters. 

Hello Biggerpockets Community, This is my first post as I am trying to utilize BiggerPockets more. 

I've picked up several really good deals because a tenant operator ran the business into the ground to a point where the property owners just wanted or needed out. 

Which neighborhoods should I not touch and which ones are ripe for the picking?

There are quite a number of things that can make utilizing an FHA loan more difficult such as more barriers during appraisal, appearance of low qualification/little cash, typically longer closing period, likely higher interest rate, and PMI cannot be dropped without a refinance if 3.5% down.That said, just chain 5% down conventional loans, and make sure your duplexes pay for themselves.  

I got into RE investing utilizing the same strategy as you're exploring.

For example, most anywhere will get $700 room, $75 fixed rate utilities, $700 deposit, and then offer a 36 months, 12 month, or month to month lease ($350 fee if ending lease <90 days). 

A couple problems dividing a property and selling in a “Timely” manner and then picking exchange properties of equal or greater value than the lots you sale.
