The smell of cigarette smoke can be hard to eradicate after your tenants leave.

Taking steps to eradicate or extricate bats.

In my novice opinion, this is what needs to be done to the house:Mold inspection/eradication (water damage from leaking water heater in attic)HVAC neglect (possible mold)10 Fogged Windows (house has numerous large beautiful windows that have become opaque due to moisture)Pressure wash exteriorReplace Carpets (approximately 1500-2000 sq ft)Paint interior walls/sand and paint trimPlumbing hardware has all been removed/needs to be replacedPool filled with excessive amounts of leaves/debris (pump is running)Excessive amounts of trash throughout house yard and pool houseLive Oak growing onto roof (arborist needed)New Sod (currently all weeds)Pool Deck ResurfacingGarage Door Openers have been removedLarge golf ball sized chip on bottom of granite on islandresurface built-insExterminatorPatch holes/cracks in walls (about 10 fist sized holes)Many light fixtures missing (10 or so in closets and bathrooms)smoke alarms missingSo, part of me was disgusted and felt very guilty watching my buddy conduct a walk through via the internet.

Lessons learned:- I really enjoy flipping a house with my own hands- I now know how to eradicate certain pests inside a property- I have gained an incredible amount of knowledge on inspecting a property to make sure it is a sound home Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

@Derek Carroll I definitely will vet the dry fog company and make sure the mold is prevented and eradicated.

Bed Bugs:  I WI if the tenants brought the pests into the unit, they are responsible for the eradication for them not you the landlord, if you spent money trying to control them for the tenant, you could add that cost is a suit if you evict, (please seek legal counsel for advice) you will have a struggle with this, but as I said see if you can get a Property Manager to do the eviction, they know how to do it, they know the law, and they know how to act on your behalf in court, you will pay for their services, and plan to retain them after when you place a new tenant, this is what they do for a living, hire a professional!

If someone says they have bedbugs, I will have it tested, and I will have the building eradicated.

The bottom of the kitchen sink cabinet was missing & had fungi growth that was never cleaned and replaced.
