I saw how he was adjusting for the comps.

What makes matters worse is that right now no one is willing to adjust the pricing because people bought properties overvalued and now are trying to sell overvalued. 

Also, find out if that gross amount includes cleaning fees or not, and adjust your calculations if necessary.

Then adjust based on the deal, inherent risk, level of experience, potential return, etc. 

We price that into the risk model and adjust our screening process.

If numbers look good there, I might adjust them a little bit to the specific deal.

My Adjust Equity if sold(Removing Extra Principal Payments over past 2 years), $26689.00My current Return on Investment ((Adjusted Equity))/(Closing Costs + HOA + Interest) is 19%.Rent: $1100 (Range is $1095-$1175 from research and property management assessments, $1100 conservative)Monthly expected expenses: $879.34 (This has Loan + Taxes +HOA+Landlord Insurance + Home Warrenty included)Annual Taxes + HOA(Covers all External including Roof) :  $2,939Monthly Maintenance: Due to being new (and External + Roof Covered) - I plan on getting a Home Warranty to cover inside appliances ($456)I have used the warranty company before and had great service. 

This is obviously based on a bunch of assumptions and I can adjust for these once I know the actual operating expenses but I made reasonable assumptions that are used elsewhere on these forums.

If not, what type of adjustment do you recommend I make to the numbers?

Might as well finance a roof with a long term loan.Related, the 30 year conventional loan is so cheap currently that there is a chance that the money (inflation adjusted) you pay at the end of the loan is worth less after the interest is applied than 1/360 of the loan amount.
