I'm not sure what market you're in, but in Los Angeles where I operate, three bedrooms are the most sought-after MTR property size. 

@Greg Dickerson Right now there are only three casitas and their 1600' prototype.

We could handle two move outs at the same time, but when we hit three at the same time we would have loved to outsource it.We would also love to have someone else hire and monitor landscaping, all maintenance, verifying previous landlords and employment, or rent collection while we are out of town.

I'm telling you, numerous times I sat with a homeowner for two-three hours presenting every solution and the consequences of what will happen if they don't do someone asap and they just don't care.

I am a traveling healthcare worker and have been for three years.

Although it is still under development there are sufficient ammenities available at the apartment project and within the community and people have started STR rentals.

Build a Strong Cash Buyers ListHaving two or three buyers isn’t enough.

On the other hand, we also had three provide cash-out refinances. 

Expanding to a three bedroom will likely attract a stronger tenant base and bring in higher rent, which makes the extra investment easier to justify over time.

Real estate and stocks are very different; see below.StocksThe investment strategy with stocks (bonds, CDs, mutual funds, etc.) is to accumulate sufficient capital to enable monthly withdrawals that sustain your current standard of living throughout retirement.
