It depends on the banks process. some have a lending committee, some have to get a VP approval some look at a chart to see if you get it.The best measure is that you ask the lender how much time it will take, if it takes longer than he says with out a good reason, you have a bad lender.

I took pictures of all kinds of issues: damage to most of my new cabinets they installed, electrician replaced a bunch of new lights and fan I had a prior contractor put in, wood trim was installed poorly unevenly cut, drywall finishing looked terrible, the plumbing they roughed in didn't line up with the vanities they knew were there to be measured... among many other issues. 

Technology and social changes are the most determining factors for respondents. 91% believe that technology will change the way we use real estate assets.Cars without driver and incremental use of car sharing, will free the space in the cities, with less space necessary for car parks.The Internet will definitely modify the real estate business, both in retail and residential.The 3-D printers will provoke that it will not be necessary to store products, nor even to move them, since they can be generated at the desired time and place.The analysis of data allows a better understanding of the behavior of potential customers, as well as measuring the experience in the process and the satisfaction of those who are already customers.

So, although I see what your measurements are trying to do, I think you'd need to run the same numbers on some other markets like DFW, Cali, Florida, Atlanta, Chicago, etc to see if its really accurate indication or if its just coincidence. 

I've seen guides that base classing basically on age, but that measurement seems out of step with the age of most buildings out there in 2017.

You could measure your kitchen floor to get an idea of floor square footage, then go to a big box store to price materials to install.  

Then I would suggest to measure a seller financed transaction against the going rate for a traditional mortgage.

Cap rate is generally a measure of risk and how much properties are in demand in a certain market.

I've been searching the internet for the method used to calculate a sensible rental price of a room for a 3 BDR Condo, but haven't found anything.I know if it has to do with the measurements of each room, the condo itself, and whether or not the subject room is the master bedroom or not.
