We added value by re-doing the whole house, installed vinyl floorings, rebuilt 2 and a half bathrooms, re-painted the whole house, replaced all the hardware in the house, installed new lighting, ceiling fans, re-painted the kitchen, and completely remodeled the upstairs.

I put in a brand new side by side stainless steel refer into the new kitchen.

Technical issues with "impact studies" results and who pays for mitigating environmental issues is another.On small projects, equipment upgrade costs for substations can be a showstopper.

New flooring, kitchen, bathrooms, light fixtures, trim, doors, etc.

This ain't my 1st or even 1,000th rodeo, so been there and done that myself and readily capable to equip clients with what it all looks like, how it's goes from someone who's done this 1st person vs theory. 

I've heard from several people who thought they had an owner finance agreement signed at the kitchen table, assumed they were paying down equity only to have the house sold right out from under them.Ben,  How common is this that a seller is willing to give up their deed upfront in exchange for seller financing.  

New kitchen, bathrooms, paint.

We put in around $30,000 to replace the roof, floors, paint and kitchen.

Bathrooms and kitchen upgrades tend to add the most value relative to the money spent on rehabs.

Pretty much all major components were newly installed / fitted and done to a tasteful standard (new metal roof, plumbing, electrical, kitchen, flooring, bathroom, doors, new hvac, decks, vinyl siding etc) and I have visited and walked through 3 times and even been under crawl space to inspect a repair that was previously noted on an inspection to the foundation after termite treatment which looked to be a good job.
