For your rehab line items, some seem off one way or the other. I would encourage you to get some labor quotes since I don’t know if you have those included.
what exactly are the renovation plans? Painting just means painting the entire home, all rooms?
Windows are expensive and I would avoid unless necessary.
Bathroom vanity seems like a lot but maybe it is a large vanity.
To give you some comparison I am nearly completing a renovation for one floor of a duplex. Here's the scope of work done:
Bedrooms/Living room: Demoed out old carpet (did this ourselves), painted all walls and ceilings, and wood trim. We got the hardwood floors refinished (we were going to do LVP, but our floors were in good shape and it was more cost effective). We removed all closet and bedroom doors and got new ones from Menards. We plan to replace all lighting and plug/switch plates. (nearly there)
Bathroom: Completely demoed everything to the studs. We had to get some rewiring done in general and for a bathroom exhaust fan that was previously placed above the shower (instead of in the middle of the bathroom). We also got old galvanized piping cut out and replaced with PVC piping. Our plumber also installed our shower mixing valve. We put up new drywall, had to create a frame around the vent of our exhaust fan since they cut the exit point under the ceiling jousts and we didn't want to cut another exit point out. We put in a tiled shower, new bathtub, and waiting on the new toilet, vanity and bath fixtures to be put in (materials already purchased). We painted the new walls and got a new secondary light (light above the mirror, our new bath fan has a light) and bathroom mirror. We also a got a block window installed to replace the one in the shower.
Kitchen: New flooring replaced with LVP, removed some cabinets to make room for dishwasher, replaced countertop, painted cabinets and replaced cabinet hardware. We still need to replace the two lights in the kitchen. We plan to also install a garbage disposal and since our floors just got finished, our appliances will be put in soon. Kitchen was also painted. I'll post some befores and afters (thus far)
Budget so far and with some more estimates for work not done yet is about $22,500. Atleast 15K of that is labor. Materials were bought mostly from Home Depot, Menards, and Floor & Decor for flooring/tile. Paint from Sherwin Williams.
This is just the work for inside the unit. We also had to replace a water heater, both furnaces and the roof. (those alone outbid the budget for the work above).
I intially thought I would spend 30K total on the the entire property, but this is my first one, and I was way off! I hope this helped. I believe we got a very reasonably priced contractor that does good work, but we had to subcontract out electrical and plumbing. The negative is he takes on a lot of other jobs, has a small crew, and our project is probably taking longer than it should.
I hope this information helps.
Not sure why I took such bad before pictures, lol.
