So HD charges the end user say $79/cabinet so no matter what the size, then they have their contractors pay on a piece base say a 12” cabinet the contractor charges 40/cab, for 15” 45/cab, 48” 95/cab.

That means driving around the area you want to invest in, writing down the addresses of all the houses that's look distressed (you could also leave notes), looking up the tax mailing address (you'll have to google your county's tax website) and sending them a piece of mail saying you want to buy there property. 

Most people say to market to your list consistently for 6months but vary the piece of mail you send.

If the house has any carpet with the dog urine smell left, remove a small piece, put it in a sealed baggie as evidence to show in court. 

It's very hard to estimate as the cost depends on panel location (how far units are from the panel), how big the units are (how many plugs in each unit), and the space the electrician(s) have to work with (is there a crawlspace they can get through, or do they have to thread the wires which takes much longer and is much harder).

Then I think you can piece a back of the envelope underwriting together and present it to the investor.

I have a piece of land under contract in a manufactured home development. 

I am looking at a piece of land that I want to develop 8,000 sqft of self storage units.

I think 90%+ of buyers want an en suite master these days, even if it is just a 3 piece with sink, toilet, and shower.I’ve done this in one of my properties and the contractor basically “threw in” the bedroom conversion for next to nothing if you are also giving them the bathroom work.
