The work will be done primarily by contractors, but we plan to do painting, hardwood floor resurfacing, and other small things.

If they are metal and sometimes plastic, you might check into resurfacing it.

However the tub has already been resurfaced once and is peeling.

I resurfaced the pool, removed a wall separating the kitchen from the living room.

Resurfacing the parking lot and adding paid storage.

It's usually when less is coming in that we spend the most time and capital.Also, since 3/7 of one building was vacant, we did capital improvements like parking lot resurfacing and new flooring and a current house vacancy needs the porch and steps rebuilt,  of course. 

Would it be possible to resurface the tub? 

Instead, we resurfaced with 350 tons of reprocessed gravel. 

So now I own a 3bd, 1.5bath single family brick ranch in a nice little neighborhood.We pulled back carpet to expose and refinish the hardwood that was underneath, completely updated the kitchen, added a new vanity and light fixture and resurfaced the main bathroom.

Some minor cosmetics to fix up on the exteriors (painting handrails, resurface the parking area, fixing some fascia boards) but it's generally pretty turnkey, and was priced accordingly.
