We are going to paint the whole interior (~$1.5k), refinishing kitchen cabinets (~$1k), updating 2.5 bathrooms (~$3k), and lighting (~$1k).

Floors, paint, kitchen cabinets ( no counters), baths etc... well about a month or so ago, after the owner had finally accepted our offer, someone broke into the house and stole all the kitchen and bathroom cabinets.

This smaller rehab would be repairing some couple foot by couple foot holes in the wall and ceiling, replacing several broken doors, refinishing the wood floors, putting new linoleum in the bathroom, putting in new cabinets (but keeping the sink) and painting everything.

I had purchased this condo 2 years ago and it looked like the Seller had just upgraded the bath & kitchen (including installing a new countertop & cabinets), at that time.4) If I’m allowed to deduct their deposit, do I just need a quote for this, or would we actually have to get the work done?

YMMV (your mileage may vary)Fixable alone: boiler maintenance and steam system rebalancing, minor lead paint sealing, plaster patching (even very large ones), thermostat installation, insulate flooring and rim joists, painting, floor repair, skim coating walls, installing thresholds, weatherproofing, installing/refinishing door and cabinet hardware, adjuster gutter drainageNeeded professionals: sewage main unclogging ($), knob and tube disconnection+removal ($$), flooring ($$), adding joists for structural support within walls ($$), replacement and removal of old brass/cast iron plumbing where necessary ($$$), new gas line for laundry and lines for appliances ($), wall demo + replacement ($$$), steam line moving and radiator repair ($$), gutters ($$)$ - hundreds, $$ - thousands, $$$ 5K-10K, $$$$ - tens of thousandsHope this helps, best of luck with the old home!

You could end up with splatters all over your floors, trim, ceilings and cabinets.

I stuck to the modern theme - replacing light fixtures from Amazon, peel & stick flooring in the kitchen, and adding a fresh coat of paint on the cabinets and walls.

I'm in the talks with a seasoned investor who is looking to slowly pass along his properties.I am in the kitchen cabinet/countertop industry, so he is a customer of mine who uses me to provide cabinets and counters for his rentals. 

i slowly upgraded the property over the 3.5 years I lived there, including building a fence, painting throughout including kitchen cabinets, adding new hardware and upgrading all the kitchen appliances What was the outcome?

My first project is a small bathroom remodel, followed by another smaller bathroom remodel, and eventually kitchen floors and cabinets, etc.
