One thing that alarms me is the entire park is rented out.

If the spore count inside the house is alarmingly high compared to the readings outside, then you've got a mold problem.I'm no attorney, but I'd strongly advise you let the tenant pick the mold inspection company (even if it's from a short list you provide), so there's no hint of perceived collusion.

Let me count the ways:1) Licensing and Entity Set Up2) Establishing Proper Bank Accounts3) Creating a Phone System 4) Having no PM education or experience5) Accounting6) Marketing - Of themselves and the homes they manage7) Application handling with screening8) Lease execution - minimal understanding of how to fill in a lease9) Tenant laws and regulations10) Tenant relations11) Maintenance (I should say that 5 times)12) Make Ready issues13) Security Deposit Itemizations (the most expensive failure you can quantify)14) Failing to seek advice or education 15) Service Animals16) Fair HousingI could go on, but one of the biggest and would considered the "umbrella".....is not providing a quality service to their owners and tenants.

If all of the individual LLC's that own the property are owned by the one holding LLC, once enough money if distributed to the Parent LLC, the Parent can then issue lines of credits to the operating LLC's which it will secure with a lien.

During the market crash, I new my neighborhood was full of opportunities, but as a single mother, I opted for security and never upgraded myself, nor started investing.
