You will find a lot of markets that make so much more sense than the insane areas like the Bay Area and NYC but also watch out for the "hot" ones since that's where everyone has gone. 

Right now, I am in the infancy stage of this idea, but we love 30A and would make sense to own down there.

This is a single family, I assume, and is it common in the area for the tenant to pay water and sewer and also care for the property?

I have been doing some education regarding the REI thru multiple books but still there are some gaps on understanding the numbers, property valuation etc. which i believe doesn't make sense until i actually make a deal work.

Run the numbers and see if it makes sense, if it doesn't, reverse engineer the numbers and see what purchase price does make sense and maybe make an offer.

Also there are no cap rates on 4plexes.https://www.biggerpockets.com/forums/88/topics/360...No trash, common area utilities, yard, snow? 

I totally understand what you are saying and it makes perfect sense.

@Evan Ventura,People here on BP have also successfully used the cheap IKEA countertops (around $75-99 for a piece). at that price they where treated as expendables (one per tenant), and some even reported getting the install time with demo at 2-4 hours.for the other, you need to "waterproof" the common points of water entry:-caulk between the wall and countertop-use varnish on points contacting sink-use good glue near the oven/range since the usual pressure-activated glue does not fare well with heat

Is there an actual reasonable fix to this or do I have to install the fancy heat sensing flaps that will close off air flow going to the bedrooms???

There are some things they have in common, others differ.
