I dont buy 4, 5 or 6% old fashion returns as the numbers do not consider the risk we are getting into, which is to have longer vacancy and bigger rotation.  

Go big, and think of how you can invest in real estate in a highly scalable fashion.

Turn off the cable, return the latest iPhone to the store, sell your jewelry, downgrade your car, list useless stuff around your home on ebay, get a roommate, whatever it is, figure out a way.

For a turnkey company to exist and sustain, they need a market where there is positive [monthly] cash flow and enough inventory to work on in a revolving fashion.

You need to pay it off the old fashion way, which is reducing spending and temporarily sacrifice lifestyle.

Runs great with minimal repairs, meets all my needs and gets me where I need to go in a timely fashion yet KBB says I could reasonably expect $1,505 if I sold today. 

Many may not require anything for a cosmetic flip, but if they do it may impact the timelineScheduling the trades- In your 2000 square foot example property we would schedule a majority of the trades in a serial fashion, not simultaneously.  

As well, those blinds will be broken or out of fashion when the lease runs out.

A HP 12C is just a standard financial calculator...Sure, you can use an old fashioned calculator to calculate everything manually, but that process can be very tedious and you can't save your results or create professional investment reports from your data.Real estate analysis apps/spreadsheets are really a dime-a-dozen these days. 

@Alex Ng Because I have worked with my contractor for about 20 years now in some form or fashion( he started out shoveling my roof), he usually walks all of the properties I look at on my initial visits and gives me a rough estimate on cost of rehab and a time frame for completion based on his current schedule and how much time he has to devote to the project.
