Contact a local tub resurfacer and they will apply commercial grade stuff that will make your counter top look like granite and is durable.

We pay a monthly fee (about $300) to the condo association for upkeep of all the common grounds, roof repairs, maintenance of the parking lot (was recently resurfaced), pressure cleaning of the outside.

Being new to this, I was really naive and thought, ok, we can replace the windows, remodel the kitchen and bathroom, and resurface the hard wood floors.

I put a new roof on it, cleaned it up and resurfaced the driveway.

Resurfaced countertops.

I do know a @Michael Whitener that does tub and tile resurfacing that really helps update a room.

Yes, you are looking at the fact that you can pay less to do a cosmetic fix, but, the problem will resurface again and most likely more money will be spent to fix it.So, take this opportunity to replace the roof now and when you plan to get rid of the property, this will be a selling point.

I had the floors resurface.

To repair the problem would necessitate cutting  and partially resurfacing the neighbor's driveway.

Is there a super spreadsheet or software out there that can handle things like:-Vacancy of single units in a multi during a rehab and the associated costs (utilities during rehab)-Projected capital expenses at a specific time...parking lot resurfacing in June of year 3-Seasonal expenses like snow removalMy point is that a percentage of something is too generic and does not represent how cash really flows.
