On a 5 night stay an erroneous complaint can sav us $1500 which is worth it for us, especially at scale.

If it is tied to the home, you have a few options:1) include electricity in the rent (down side with that is tenants may be less diligent with electricity use and increase the bill)2) have the tenant pay it and include a copy of the statement every 1-2 months to show that it is paid in full.3) have the bill in your name and send a copy to the tenant each month (or whatever the billing cycle is) and they can add the balance to their rent each month. 

I'm hoping to start my career in either metro Dallas-Fort Worth or Chicagoland, and my main priority to is to minimize my housing expense with roommates while building equity and learning how to be a competent landlord.

There were 2 vacant lots that closed across the street for 1m and 2m, so we knew the land alone was worth 1.5m minimum, plus there was a small house on it already.

Increased the rents, decreased expenses.

Thats a good point, so yall find that following a call with a brief text isnt really worth it to much? 

But if I'm limited to 25%, I wouldn't be able to contribute nearly as much to make it worth it due to paying self employment taxes on the other 75%.

I've been down that path before and its not worth the time and energy. 

It's not worth risking the invalidation of your IRA account which would cause penalties and taxes.  

Ten homes worth about $50,000 each, all of the homes are occupied.What would be a deal-killer:1.
