Where can I find some literature or any form of education about what currently builds equity during renovations…i.e adding bathrooms, custom closets, adding sqftLeaning towards a flipping market..I want to make sure we’re working smarter TIA

To enter the inside of my thought process: Check the real estate listing, count how many rooms there are, condition of appliances, cabinets and bathroom. 

Rehab is likely 6 figures (open the layout, rehab pool, rehab kitchen, rehab bathrooms (3) converting one bathroom from 0.5 to 0.75), new and relocated HVAC, Digital locks, patio with deck accessible from Master BR, convert office to BR, convert large BR into 2 BR).  

New roof, plumbing, new kitchen, new bathroom, paint, new floors, LOTS and LOTS of cleaning What was the outcome?

I bring in over $1000/month renting a room with a private bathroom.

Cracked floor tiles in the 1/1 unit's bathroom - noted that it may be due to sinking of floor 3.

They are in fairly good shape, but the kitchens have limited cabinet and counter space, and both the kitchens and bathrooms are dated.

How to have this discussion with sellers in a way that doesn't seem like you're trying to get property at a steep discount.

We put a lot of work into the kitchen (painted the cabinets, new flooring, new appliances, new sink / faucet, new lighting, wainscoting, new paint) as well as new flooring in both upstairs bedrooms and the basement, new vanity / faucet, mirror, paint in the main bathroom, completely repainted the entire inside of the house and 75% new lighting throughout the house.

Use a Realtor, negotiate a discount.
