The downside is that you have to deal with multi-tenant issues in the same building and finding comps can some times be a challenge both when you buy and sell, and since there are fewer comps, the prices can swing more than with single family.If you've got experience with plexes, I think you'd find SF rentals to be much easier to deal with because there is only tenant. 

@Terri Hoffort:Hi Terri,It might fit into the neighborhood better, if a lot of people also have railings--or start a neighborhood railing trend.And the under porch fancy stuff, typically gets nailed on from behind the porch floor beam vs in front of it, and the bottom should miss the dirt by a few inches to prevent decay.Access--there is usually a window in the basement you can get through under there, or have one of the sides hinged so it swings up out of the way, because if leaves accumulate under there you (might) want to remove them.Good Luck!

There are many that wish to sell and trade up right now but they don't dare do it because they'd be homeless if they sold right now so we just have to wait it out.All of that means 2 very important things for investors - Appreciation is fantastic and rents/sales prices are climbing so your returns in this area are guaranteed to produce!  

It is good to hear from someone in the trades here as well as it doesn't seem like enough of them are represented on this site.

So I’m selling two seasoned rentals and aim to trade them for 4 units.

Then when you have enough equity in that same DST trade up for a bigger multi family??

You could sell and trade up, but I would prefer to refinance and buy more.

In countries like Mexico, Costa Rica, Panama, Dominican Republic or Uruguay, the properties that you'd buy are traded in USD.

There are a few of the larger service companies out there that offer many of the trades under one roof.

We would be able to consistently add capital to our investment portfolio yearly, let's say $10k per year.Some strategies that have peaked my interests are SFH or small multi-family BRRRRs, short term rentals, trade up into large multi-family, rental debt snowball, etc.
