It sounds like you invest in what others would typically call c-d on that a-d scale, meaning lower income areas with higher crime resulting in a perceived less desirable tenant. 

If so, it seems like they are not marketing to the vast majority of potential buyers (because even these big players have <20% market share in any given market).

You can engage another PM company to manage the new properties and this will give you a backup/bench player and keep your checks and balances.  

@Stanley Bronstein  @Jay HinrichsTen years ago Texas changed CD law so it eliminates almost all the abuses, but still maintains the essential element of allowing people unqualified for financing to purchase a property.The law that accomplishes all of this is astonishingly simple.  

The team wouldn't succeed if it didn't have the right team players in place responsible and executing on their roles.

One thing I'd recommend to ya is to get around the MAJOR PLAYERS. 

B, C, D class neighborhoods.

Kind of like with stocks/bonds/cd investments. 

Question for you pros: if you had 50k cash to get started investing, would you purchase 1 home for cash in a C-/D area or finance the purchase of 2 homes in a decent suburb with 20% down each?

Even though I haven't purchased my first property yet (waiting for June when my downpayment money matures in a CD) I have a schedule of research and regularly meet with other investors and keep track of my educational process.
