Your entire package comes with a 30-day 100% money-back guarantee.Incidentally, your guarantee is void the second you break the seal on the package they put in your hand after you sign your credit card authorization and contractual agreement with the fine print.I went to one of those snake oil shows where in the first ten minutes of his presentation the promoter told the members that the course was something like $50,000, but the first 10 buyers could have the course for only $8,000.

@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. 

Dog chewed up a window seal and an area of the real hard wood floors.

Basements can be sealed from the exterior.

@Brendan Seals a new AC/Furnace here for that size house recently cost me 4k and last month I had a new 40Gal. hot waterheater installed and it cost me $1000 (which is up 20% over the last  year).

envelope not sealed?

Seal the impacted area.

However, if the pest problem resulted from a defect of the property (crack in the foundation, a window needs to be sealed, etc.) then that is when the owner pays/handles. 

This meant making sure all pet food was stored in airtight sealed containers, keeping hay in containers, being diligent about not leaving food out and taking our trash timely, and also making sure a side door that was often left ajar was tightly closed to not allow an access point for pets.

I can't speak directly to what it will do on appraisal but I will say generally tenants in these markets just want to see a 'clean' basement with sealed & painted walls and plenty of lighting.
