According to my contractor, the fix to prevent further damage seem to be simple, seal the gap between the trim and window, clean the gutter, and replace the drywall on those areas if needed.

Should have found a handy man and ordered some flex seal and make do with what you have... partly a joke but also if the quotes were more than the funds available than you should have found another fix since there should always be a reserve fund for the next issue to come up so I would have suggested a temporary fix <2000$ like caulking and flex seal etc...

.- If that doesnt work, then seal and paint for odor control.I would deal the same way with an apartment after a smoker.

You can get a corporate seal at Office Max or Office Depot.

Improving the building envelope - air sealing, greater insulation - will give you more bang for your buck.

Hey guys I am finally breaking the seal and jumping into the cold waters.

I have determined that, right or wrong, I'm sealing the deal on an investment before year's end.

America.but must air seal as it will bring warm air from conditioned spaces to basement. dehumidifier produces heat as by product, and takes more electric to operate. if go with dehumidifiers get large comm heavy ones with humidistat and direct drain. no one will walk away with it. 300lbsdont just open window unless dry air cat 1 wind blowing straight in.it wont remove moisture only feed it. i use activtek  air scrubbers secured to a bracket holding plate. it kills protects 2000-10k sqft of mold bacteria, and reduces moisture as its byproduct of technology esp basements.

Fix the baseboard molding with Bondo, get rid of the laminate flooring and replace with luxury vinyl plank flooring or sealed-in-place triple-polyurethane-coated solid hardwood if you're going to allow pets.

Possibly justifying higher rents and lower vacancy.In the end, it may be worth pricing out a deep-energy retrofit to super insulate/air seal the property and drop your costs.Good luck and please let me know your thoughts / what you decide.
