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. 

A lot line adjustment is the easy fix here and you already have the surveyor to give the legal description for that transfer. 

Once you have it written and have run through it a few times, you can make adjustments/improvements to the process. 

Adjust the filter settings to include only Sold properties within the past year and then throw a couple more filters in.

Offering free rent is the same as lowering price. adjust price weekly based on showings.( Tenants call based on Monthly rent).

@Tim Johnson I have seen that too, but the explaination I got was that they have just put it on hold for now more because they have so much work with adjusting existing loans, so its a manpower issue.

Only a handful of apartments entered contract these last couple of weeks, so it's too early to guess how and if the market will adjust.

I will adjust the interest rate to something a bit more realisticI know that I will have to secure accurate comps from my agent, but I was wondering what your thoughts are regarding the Zestimate on Zillow.

I have a HELOC with an adjustable rate, which the terms clearly state is pegged to the prime rate plus 1.99%.
