We have 43 listings now, have a full-time managing partner, a couple assistant managers, 5 cleaning teams with 16 cleaners, an office, and for the sake of vertical integration, we’ve been shopping for laundromats for our linen solution.

I have a contract with an HVAC service to clean/check each HVAC system twice a year (typically at the beginning of both hot and cold weather); they also make certain those filters I leave tenants actually leave the box and end up in the return during these checks.Some Property Managers do monthly check ups: these tend to be done more in apartment complexes than SFH. 

Won't require much of your time, hire a cleaning crew, do the management yourself (couple hours a week)Just my .02

After they are gone, apply the deposit to the unpaid rent, cleaning, and repairs, and then decide whether to go after them for any unpaid amounts or if you'll just let it go.

I recommend David Greene's "Long Distance Real Estate Investing" as a starting point.

I have seen the property and it looks like all it needs is a little rehab; paint, carpets, and the yard needs cleaned up.

This just means in some sort of audit or lawsuit, your personal banking records will be needed to show the movement of funds to demonstrate that everything was done cleanly/correctly. 

We all know green and open spaces increase neighboring property values.

An attorney will draw up the mortgages and it keeps it clean.

Note of caution; understand your foreclosure laws, depending on where this is in the process, attempting to pull investor ploys without having the ability to purchase yourself as implied under the contract can land you up against federal law, a lender can clean your clock for interference with an insured depository.In other words, investors who lack the ability and intent to buy themselves as stated in a contract with someone in foreclosure should stay clear of any attempt of trying to pull off anything except a true a cash sale.
