I'm a number cruncher as well,  I always like to measure Cash on Cash Return, that's my fav number :) What is your key metric?

Also I should point out it was advertised as being 575 sq ft, so when the living space (tax office doesn't care about living space, it counts the outer envelope) was measured it was a good 100 sq ft less than what I thought I was getting.I also figured I'd use the small size to my advantage.

I'll have to add IRR to my calculations so see how things measure up.

These goals should be very simple:1 - You need to pay off all your personal debt2 - You want to have enough passive income to cover all you monthly bills3 - You want to accomplish this by a specific date.4 - You want to have fun doing this.Once you set these numbers, you "reverse engineer" from there, establishing as series of groups (elements of the steps above) called "measurable milestones".  

You cant manage what you cant measure - order a home hygrometer for $10 online and measure the relative humidity in the house.

When I did my first flip I measured up things like rooms, counted doors and sizes, measured windows, etc...

Does anyone use any form of 3d measurement devices to take measurements that can then be uploaded into a design software?

Your Financial Goals are as simple as generating two very basic sets of number...dollars really:1)  Make enough Profit (lump sum returns) to Pay Off your personal debt...ALL of it.2)  Get enough CashFlow to "cover" your monthly bills...ALL of them...and to replace your current method of doing so.The overall Plan, is comprised of a series of Measureable Milestones made up of groups  of the individual Financial Goals (Debt Payoff, Cash Flow)...all lined up in a row.  

If the house is really old and has asbestos and other things then it generally costs more to remove as you have to take additional measures when tearing down.Grade costs and topograhy is another issue.

FORECLOSURE: A seven year waiting period is required, and is measured from the completion date of the foreclosure.A three year waiting period is permitted if extenuating circumstances [EC: non recurring events that are beyond control that result in a sudden, significant and prolonged reduction in income or a catastrophic increase in financial obligations]  can be documented and the lesser LTV of 90% or the standard product guidelines.
