I have meticulously designed, built, decorated, furnished, cleaned, stocked with hotel-like essentials, cleaned again, and published my property as a vacation rental on AirBnB.

I was also only there for 6 months.When I finally got the deposit that, an extra $40 was taken out for "cleaning" making the total for "cleaning costs" $125.

Day 3 I hired 4 guys from Home Depot parking lot to help clean up the back yard.

They’re using her money to clean and try to get the place rented again by the 1st.

So I'm finding several properties on my local MLS where it looks like a rehabber has purchased a property, did the demo work, cleaned it up, put on new siding, exterior windows, sometimes a new roof, framed out the structure, and now are advertising it for sale at this point.

  $70 for cleaning sounds right.  

Nothing worse than stained carpet and if your place isn't spotlessly clean, you get bad ratings. 

You may want to research the Clean Air Act.

This strategy is generally used with a balloon payment in 3-5 years so that the buyer/tenant has time to clean up their credit and qualify for a mortgage. 

Wil the agreement allow the other side exit cleanly and finish what needs to be done?
