I'd probably also select an outfit that does the management.  

Try to get to the other side as fast as you can (that is, get beyond trying to own 65 separate houses in a 20 square mile area, and dealing with a PM and a handyman outfit).

Or a similar out fit?

These aren't newbie investors, these are major outfits. 

There are still some truly high quality TK outfits around -Spartan (of course), Memphis Invest, Decas etc - but unfortunately investors do need to take ownership of their due diligence to avoid these kind of scams that are all glossy marketing and no substance. 

I currently have over 30 units, just under half of them are managed between 3 different outfits. 

Homebase.ai does a good job with this handoff process for locks in large multi-family properties and enables smart home move-in ready apartments if you ever decide to outfit the units with smart devices.

I'm sure this varies, but I've found that smaller outfits will give you better prices, though service is sometimes slower (which may not benefit your situation).

However your correct there are many that do 40 to 80 units a year.. so in contrast I guess you could call them small potato's  but that does not mean they are not great outfits that do a very good job for the Clients.

Do I really need to outfit my shower stall to the same level as shown in the image?
