The 900 square fee would adjust up to simulate both comps being the same size.

@Albert Bui I just went through the simulator in www.aioloan.net, and the result was amazing!

Painting the pipes I learned when I started lending money in Detroit.. and they painted them grey to simulate lead pipes I guess.. but white works as well. 

But when I was using Turbotax to simulate a mock return, it seems that Turbotax offsets the C corp's rental loss against the C corp's income from regular business and trade.

I would use the same lease or something similar and add your own simulations to make it more bulletproof.

There are too many things that could go wrong with this method, which is why I switched to simul closes.

Cash flow and appreciation.In general, even leveraged cash-flow property can not outperform S&P in total return because their appreciation  for 16 years is so low in term of absolute dollar (due to R&M).While leveraged appreciated market could outperform S&P in many ways, in gross it's similar to be having 15% CD in environment where yield=2% One could simulate this using ZHI.Property that can beat S&P is always always expensive top tier homes price 300K in 2009-2010 and appreciates more than 20% IRR from that time.Once IRR is below 10%, S&P would perform better because its appreciate 7-8% annually ( even better if one absent not to particpate during the bad times).

I live right next door and will be repainting, replacing flooring and doing some minor modifications.My home will be a short term min 2 night stay max 1 month stay (extendable month to month) furnished rental.I have just about completed moving out of the 3/2 1900 square foot home.I plan to rip up all carpet and sheet vinyl and install simulated wood glue down vinyl throughout the entire home.

There is a credit score simulator on Credit Karma. 

It sounds like the technology has been proven so this might not be an issue for you, but one thing we found was that our technology was much more difficult to apply in the real world rather than our simulated sample sets.
