Class A apartments have numerous amenities, professional management, and sit in desirable neighborhoods.

I don't invest in section 8 housing and also have no desire to so maybe I am biased.- I live in Raleigh, 10-50 unit complexes will be hard to come by unless you're okay paying a premium.

It has to be in the most desirable/expensive areas of the country.

It is in an extremely desirable area in Watertown, CT. 

In my take, I'd buy Pine (which is 5/2 2700sq ft) than Byrd (3/2 1832sq ft)- But the price differences may be due to desirability of neighbourhoods (someone takes about crime in Niagara NY)Also, 353 Buffalo Ave, Niagara Falls NY 14303 (5/4,5 3255sq ft) is selling as an AirBnB for $749,900 on Rabbu> Ann rev @ $63,755 and gross yield at 8.5%.

Second link is a similar size, albeit 10 year older home, in Setagaya Ward (a very desirable neighborhood), but still "only $1.2M. https://www.homes.co.jp/kodate...https://www.homes.co.jp/kodate...(2) Age. 

The new design takes the home from a 3 bed, 2 bath to a 4 bed, 3 bath, 2,400 sq ft rambler on a large lot in highly desired area.

I don't necessary want to quit my job but having the option to do so is desired.

There are pros and cons but i believe for most properties the cons out weight the pros.
