In my opinon, we both bring certain value, and there’s room for both of us to operate in harmony. idk why all the hostility. 

And not only have I picked up quantity but these 11 homes are easily the best product of my entire portfolio.

I would like to work exclusively with a couple investors that pick up large quantities of properties once or twice a year either multi families, commercial or land for development. 

It's sounds like the wave of buying by Blackstone and other institutions since the housing crisis is now waning and that in places like Atlanta - which is my hometown and a market I am particularly interested in - they are now selling off large quantities of less desirable rental properties.

I'm working on doing quality over quantity deals.

With those factors in mind, I think it's really up to you to decide if:a) your market can support five similar units and you won't be taking business from yourselfb) the additional time/effort/expense of running STRs is worth the projected cash flowIf you're confident your market won't be fazed by the quantity of units you'll be putting up (which I assume are comparable to each other and thus will compete with each other), and you feel confident in managing that many units, I say go for it!

I suggest to also look at job growth, crime, the quantity of ppl that own their homes vs rent in your area of interest.

If you go that route, I'd suggest getting a small quantity made first, or see if you can get a sample.  

Quantity of offers means everything.
