I have four sfh rentals in one neighborhood in Gainesville, Florida.

IF what the seller wants fits under that number it is a deal.

Transient traffic can make for an unsafe neighborhood for neighbors as they no longer recognize "regulars" to the neighborhood...traffic...blah blah blah...the good side? 

It may not even be legal in your neighborhood.   

Make sure the neighborhood is something you like and the market is one where you see promise!

Let’s say we find a 4-Plex in a neighborhood that I’m interested in.

I'd recommend the flipping route so you can secure more cash to use as you see fit as you grow your investing career!

As a first approximation I'd probably take records from the largest time frame available, do a linear fit to that and assume the same percentages can apply over the next 20 years.

I wouldn’t at all recommend that you go with someone that doesn’t have any experience, when someone hooks up a water meter incorrectly and or forgets to put stiffiners in they poly lines before putting on the copper fittings, you will be digging it up eventually to fix some leaks.
