It will affect a segment of the market but but not all.

I agree with others that the land will still hold value and I don’t see the electric car thing affecting this segment very much.

Going forward, we will continue to see large groups of independent agents branding themselves to a niche segment of the market or a specific type of relocation.

Unfortunately, it is too long to present the entire story in this Economic Update, so I will break it up into seven weekly segments.

And there's a lot more volume in the 3-4 unit space than in other segments (so many more opportunities to close deals and earn money, rather than relying on landing a whale once or twice a year).Furthermore, experience in small multifamily could obviously lead to an opportunity to operate in the medium to large multifamily space, where the analysis is much the same, but the numbers are much bigger. 

Where you invest is not something I can really help with since I am only in sub segment of Saint Louis. 

Small towns may rely too much on a single business or market segment.

Has anyone come across a course that's more focused on this segment?

Has a few segments on Boyle Heights too. 

I agree residential rental properties are one of the least speculative segments of the RE market, but where I've seen investors go wrong is to sell A area assets towards the top of the market and replace them under pressure in B or C markets in order to chase income.If you can borrow the equity and have your BH tenants pay for that borrowed equity in the form of rent, you can use that free leveraged equity to find return elsewhere (B and C markets).
