That didn't seem too bad but my analysis of the property told me I'd only get an extra $100-200/month in positive cash flow out of it.So I decided to hold off on the major renovation and do a simple clean up and repair the minor issues for $5,000 or less and get tenants in it asap.Meanwhile, about 1 week before closing I posted a ghost listing (just a simple "for rent" listing with a photo of the front of the house and some details).

If there's existing contamination, cleanups can be catastrophically expensive. 

How do you handle dirty work such as debris disposal and clean up?

The PM verbally stated no charges would be due after pro-rated rent was paid & tenant moved out.The PM company billed the widow for damages for cleanup by a remediation company.https://bit.ly/2wR9PXu

Clean up the space itself as well as the overall property to show it in its best light.

I think the first refers to Prop 36, the clean-up/seizure of a drug lab http://www.capcentral.org/high_court/arc_2005_cal.aspxThe second one looks like public storage facilities and the third involves settling an estate.I would check into the third and probably avoid the first....it will be tied up in legal proceedings for a while.

Gut rehab kitchens and just clean up bathrooms.

I also highly endorse Jonathan Hoover with Aegis Environmental if you need help in Indy for underground storage tank remediation and for all of your other environmental cleanup needs.

In my single family houses the tenants are responsible to mow the lawn (they supply their own lawn mower) and do simple gardening chores/clean-up and rake leaves and shovel snow.

Also FHA has the highest debt ratio allowed at 56.9% and FHA will also count your rents from the other units, helping your debt ratio.Fannie Mae and Freddie Mac will also count income at 1 year showing on a tax return but their debt ratio max. is 50%There are several programs in Non-QM loans, such as 12/24 month bank statement programs. you can also do a Asset depletion program that takes any liquid assets you have, divides it by 60 months to derive your monthly income.
