They will be owners in both the sides; normal rentals and short term rentals that are going to need to off load and I feel the airbnb crowd will be the first to start the fire sales..

How do I structure a fair and decent term/s for items like roof and HVAC?

Here's a link to my estimated calculator report if you guys are interested: Portland Duplex Austin- I was able to shave off $4000 based on the inspection that suggested I needed a new roof within a few years.

The owner told me she just replaced the floor, roof and heater/ac.

I learned about wholesaling through many YouTube videos and became quite obsessed with the topic, I figured I could probably do it my self and do ok but I realized if I want to be great im going to need a mentor someone to teach me the ropes and ins out outs of wholesaling and fix and flips someone with experience who will transform me into a real estate guru I am willing to work hard and show up everyday to learn new things.

Complete remodel from roof to basement and everything in between - new kitchen and bathrooms, flooring, light fixtures, paint.

Do you know the condition of the roof, water heaters, etc?

If that prediction is anywhere close to accurate, we are going to need a lot more stimulus than just $1,200 and unemployment insurance.

Construction (stucco siding and tile roofs, I have several 20 year old roofs that should go another 20 years in their sleep, I paid $7500 to reroof a 12 year old property on MN) and age property.

A couple of thoughts:The best quote I recently received for a roof (1,700 square foot ranch - SF BayArea) was about double that of your budget item;  the electrical line item also seems low based on charges I am seeing up here ($100/hr -$120/hr) and what I understand will need to be done (essentially wiring an entire house)
