@Sam Ojo this sounds like a broken condo deal—which is a situation where an apartment complex has a condo map and some units were sold but not the rest.

I did contact the agent I originally purchased with and am working unofficially with him to get quotes for kitchen upgrades before prepping the building for sale.

The sellers recently installed new forced air heat in all the units and the electrical service has been upgraded.

A guest might say "this is broken" - if I was 15 minutes away, I would still call the same handy man.

Because they didn't approach us until they've broken ground that I am unsure of the reasons why... but my sister and I will be looking at building plans, proposals, and any amendments to the original plans to see what's going on and hopefully resolve this soon.

(Toilets are a big one)- Deteriorating paint (lead is extremely common in cities like Rochester)- Breakers, furnace filter(s), water heater(s)- Damaged/broken stepsI think it is a little ridiculous to go around and nitpick with a checklist, but we do check for issues that would cost us money down the road, or are safety issues for our tenants (and properties).

@James Webb Yes, it can be broken down by sq. ft.

I own a SFH in Los Angeles and am thinking of making some upgrades-1) opening up a retaining wall that leads into the backyard and install a sliding glass door2) adding a 10x12 wood floating deckMy questions are:1) How would I calculate the increase in value for these upgrades?

It is an owner occupied property(me, I am house hacking)  The kitchen is very dated so I will be doing some upgrades.  

The house has good bones, but has “toxic mold”, an old septIc, broken well pump, etc etc.
