Well, it could increase it because you're collecting more rent, it could decrease it because you have more expenses and/or more paper loss (i.e. depreciation), or it could all come out in a wash if your increases in rent approximately match your new deductions.Let's say for 2020 you have $100,000 in profits that would be taxed at whatever your tax rate is. 

The home was inspected and there was one area inside a laundry room wall where a toxic mold was found.

I think it would be invasive though for existing tenants but they might be cool with it since no more shared laundry or worse yet trip to a laundromat.If you cut the expenses down for heating I would cut atleast 100 probably 150 off monthly utilty bills from metering electric heat.

I saw it says basement is open to both sides, you May also be able to look at other income opportunities there, laundry, storage, additional bedrooms or bathrooms, etc. 

When it was all said and done it was pretty much a wash.

Of course the tenant denied the extra people....she even said that one of the extra beds was for her to fold laundry on ;)So the easiest eviction is non payment of rent, or anything else in your lease that is described as "additional rent".

If so what about pressure washing the home?

I kept the 3 bedrooms upstairs but turned the large den and laundry room on the bottom level into a spacious master with master bath and walk-in closet.  

I'll power wash the mold of the siding, put in some light bulbs, have the electric and gas and plumbing turned on (HUD winterizes houses) and get a Certificate of Occupancy inspection.  

I need some one who is dependable, handy (can touch up paint, fix leaky faucets, power wash the porch, or whatever else is needed) AND has good people skills in that they will be working in two small senior care homes with Alzheimer's residents.
