When in the past they just e mail and agent who puts them on listing auto notifications I know my inbox is stuff with those in the 12 markets I work.. not necessarily to purchase but to keep up on values.

I would say to watch out for the trap of looking for the absolute cheapest property, and instead look for a nicer (but still affordable) area so your tenant quality will be higher and you will have more stable rent and property appreciation.

Hi @Stephen E Drew, the most straightforward approach would likely be to consider 1/3 of the purchase of the new property "boot" and the other 2/3 a valid 1031 deferment.Boot is any portion of the proceeds of a sale that is "taken out" of the deferment exchange or otherwise doesn't qualify.For example, person A sells farm and buys an apartment building of greater value and daddy want a Caddy, so he goes and buys himself the whip of his dreams. 

Rochester has reasonably priced property and a stable population, seems like a great place to begin.

A survey by AFIRE (Association of Foreign Investors in Real Estate) discovered that 58% of people consider the US the most stable place for real estate investment.

According to Internal Revenue Code §168(e)(2)(A)(i), “residential rental property” means any building or structure if 80 percent or more of the gross rental income from such building or structure for the taxable year is rental income from dwelling units.  

We have a small career field and when we were newly married E-4s, a E-5 told us that she'd bought a house at her various duty stations. 

As noted by @Lynnette E. for CA,  there does come a point at which counties in WA will not let just anyone pay the property taxes.   

Next few years, will be difficult for many as the economy goes into a recession, but you'll have a stable job, access to great loans and in markets with heavy rental needs (areas around bases).
