You may have heard the old spiel about dealing with "tenants and toilets" from guys like Scott Meyer who specializes in self-storage. 

My housekeeper does this - paper towels, toilet paper, tissues, dish soap, hand soap, laundry detergent - all are EITHER included in the base price OR itemized on my invoice when they are incurred.

As for the leach field, there are ways they can detect those, by doing a radio controlled device flushed down the toilet and following it to see where it goes, etc.

This is the simplest method, but it also means your tenants are more likely to abuse the utilities by leaving windows open with the heat or A/C running, leaving lights on, ignoring the toilet that constantly flushes on its own, etc.3.

My goal is to rent it out and in my market I can expect around 1200-1500 in rent if I accept section 8.Details:-2bd 1ba single family-renovations: new ba w/ floor to ceiling tile throughout, new vanity, new toilet, new lvp flooring, new carpet, new roof, new lighting, new water heater - built in 1912(I visited the property and the only thing I noticed was that the windows had not been replaced, and there was no central air although there were cooling units in each of the room.)I’m having trouble formulating an offer amount and terms because I don’t know how much the owner is all in on the property, and what should the terms be for this type of deal.

In effect you'd be squatting in the prior owners home, renting it out.  

Mortgage: $2,634Utilities: $300Misc: $300Total: $3,234The misc. is things like toilet paper, paper towels, coffee, sugar, linens, batteries for remotes, laundry detergent, soap, etc., etc.

Site preparation - install temp power pole, stage const. office trailer, install site fencing, stage temp. toilet, install erosion control (straw waddles, silt fence, rock entry), install temp water, install site web camera.The other major task group we are working on is the selection of subcontractors, and if warranted, a general contractor. 

A little bit of googling tells me that we need assistance finding those that may be ready for purchase, but not on Zillow, since squatting is not viable for us!
