id make offers, from your home office, on reos, on market mls, (not off market stuff) use internet, zillow, pics, now more vid support, google maps, with goal of acceptance and 10 day Due diligence , ..you might get 5-10% off retail list price,  then have inspection, with support of agent. 

My personal feelings are that you are attributing too much emphasis on what you can prepare for by  learn from a book and the internet, etc,  and calculate from a spreadsheet.  

This is my first major rehab and just want some help with the new layout I am proposing (See images below).The property is very small, ~600 sqft.

A comp is same size, same BR, same BA, same multi-layout within 1 half mile of the property and sold or closed in the past 3 months or 6 if necessary.

I have an opportunity to purchase the house next to my mother's, near identical layouts.

Is there an issue with the layout? 

Check and double check cabinet layout, oven door didn't clear handles on cabinets, problem solved but not easy.

@Danny Mak we have definitely updated all of our listings to reflect that we can accommodate WFH stays (fast internet, etc).

I'm sure there are copies of the systems that hotels floating around somewhere on the internet. 

There is surprisingly little detail on the internet as it pertains to this county.For example a 2 family with an in-law suite - Can all 3 be rented out?
