Relationships and networks are key when you don't have experience and a bunch of money bags.

🤢🤮There aren't enough bags in this world. 

And, once all the covid dust settles and there aren't companies trying to grow their biz by losing money, said Realtor will get that future business.

Great flashlights and extra batteries that fit, super long extender ladder, korkers/or other brands over shoe to go over your steel toe boots, GFCI tester, moisture meter, a dog nose, an extender mirror, shovel to check foundation moisture, respirator as some properties have gross smells or chemical exposure, regular retractable tape measure forget the laser one, 5 gallon bucket, zip lock baggies, brown paper bags, putty knife, variety of screw drivers,Are you checking basements?

@Timothy Burnes Don't do it. 10-20k in equity is not worth all those issues.Bed bugs are a significant defect that can take either $5000 and tenting the whole building for heat treatment, which requires vacating the tenants or getting them hotel rooms for a few nights, or a sustained program of prevention with bed risers, leg traps, sealed mattress bags, and the tenants need to keep it up for.. get ready for it.. 6 months, which is how long they can live without a meal.Sewage in the basement could be a big issue if you have a sewer backup problem.The sinking toilet sounds like it needs immediate attention, but at least that's a straightforward repair.The other issues are what I would consider "normal" as in, you could fix them but don't need to in order to make the place liveable.Based on the bed bugs alone I would avoid... if you are comfortable with this level of rehab you should be getting a way better deal. 

@Veronica Thomas I have them sign off on a checklist through docusign that has a check-in / check-out column (fans dusted, floors mopped, self-cleaning oven cleaned, shelf out fridge cleaning, microwave inside clean, toliet scrubbed inside and out, cabinets crumb free, no chemicals/furniture/toliet brushes/brooms left on premise, no large garbage items on street curb, etc, etc) .

Can you lease the place from her for now, rent it out to generate income for you and payments for her, then buy after the dust settles?

I'd lean on them to do the heavy lifting upfront, then on the back end when the dust is about to settle and your final signature is needed for something, I'd loop in a lawyer at that point (if not earlier) just to keep everyone honest. 

They have 2 pet rabbits (the lease allows small pets), they had a bag of rabbit food tipped over and spilled in the cages, and hay outside the rabbit cages in an open bag and also sprawled out on the floor of their kitchen.

Workmen would need a respirator while working with the asbestos, and the asbestos would need to be bagged and disposed of with a special landfill.
