I remember not long ago when that part of DC (near RFK/Stadium Armory) was “undesirable” to some.

With so much talk of multifamily investing, demand has been high for 2-4 units with only properties having fundamental problems still sitting on the market - either structural issues, undesirable location or seller not willing to budge on asking. 

Look at SF  Portland and Seattle.. big movement back to the burbs because of companies leaving. now they are leaving because of defund the police and homeless and other social issues have made living there undesirable to many..

It goes on to discuss how later current events (world wars) and economics led to these same "undesirable"  non Anglo-Saxon Protestant immigrants being allowed to eventually assimilate into whiteness.I understand that some of you all had it rough growing up.

Meaning, if you own a larger portfolio and 1 property is experiencing undesired returns.

Quote from @Michael Baum: I think building in commercial zoned areas for the most part will make the STR a little more undesirable. 

These circumstances center around property that’s so low priced, needs so much work, so unattractive to home buyers, or so undesirable a location, that COMPETENT realtors are not interested in listing the property, oR acknowledge that an offer is not likely in a reasonable period of time.  

We bought a undesirable commercial lot, rezoned it to residential,  and we can put 10 units on the lot.

The days on market might increase, and there might be a good chunk of those that remain undesirable or bad deals.So don't over-leaverage, and be ready to jump on investments Q3 and Q4 2021 depending on a number of factors still to be determined.

Maybe that advice would normally be a good rule-of-thumb for most people in most situations, but what if someone finds a good deal in an area deemed "undesirable"?
