Just ensure the agreement is clear and formalized.Pooling reserves across properties might make sense if you’re confident in your cash flow and other contingencies.

You're on the right track to reach out for help here and also to look to your area for potential partnerships.

I don’t have any legal advice, but maybe some helpful perspective.When we return security deposits, we write the check to all tenants on the lease, such as “Tenant A or Tenant B”.

This is not the utility company's responsibility.Your lease should state the tenant is responsible for maintaining utilities.

I lived in Houston for a dozen years (moved last summer) and really wanted to make an STR work, but I just couldn't get there.

You need to follow through. 

I agree with the others.

We were initially looking out of state for a potential move and or investment property just because the property taxes without being able to homestead, plus high cost of insurance, and harsh weather on homes made me feel like it might not be worth it.

Just say no and move on. 

Just get you in, and then you got to worry about the problem after.
