I got very disappointed with the fact that I’ll have to deal with the smell and am afraid it is a threat to my health.

An architect could very well fill the voids you may have for the home's demolition plus other related cost for jurisdictional approvals (Building Department, Planning/Site Plan Review, Department of Health, etc.).

Water heater, roof ceilings from inside, tub, under sinks, everything you can access.

They also pay all their own expenses like health and car insurance, errors and omissions insurance, umbrella insurance, Realtor’s association fees, MLS subscription fees, monthly desk/technology fees to their brokerage, vehicle maintenance, clothing, marketing and business expenses, retirement account, etc.

Evictions were only allowed for health and safety issues.  

The contract says inspection requests may be made for "health, safety, and structural related issues only" but I don't think the seller is contractually obligated to make any repairs. 

Walked into the other unit and not even in the kitchen we look in an open closet and see a large Tupperware tub filled with water and about two dozen bluegills. 

There's definitely data that supports a hot tub vs. no hot tub.

You basically have the idea down, yet you may want to have the Management company NOT owned by the owing entity as well you may want to structure the ownership entity as a Corp, so that you can #1: collect a W2 #2: contribute to a solo 401K #3: Run more personal expenses through the entity for tax write off options such as health ins. and other insurances. 

I have my broker's license in CO but it is inactive and I'm going to keep it that way for the time being until I start to get some deals going, having access to the MLS would be an incredible tool though as well as being able to use showing time to schedule my own showings.There is actually a property I was checking out yesterday, the listed price is far too high for a flip based off of my rehab estimate but my estimate also seems quite high at 86K for a 1007sqft ranch w/ 3bed/1bath.Would pretty much be a gut job, all windows replaced, carpet removed and hardwood refinished, full kitchen/BR remodel (kitchen is 10x10, BR is 10x8), driveway and entry sidewalk repair, possible foundation issue, new patio or deck, and then landscape cleanup.Roof is in pretty good condition, there is water damage in the BR around the tub.
