Get your money squared away 1st.

Recent comps I found sold for $61-66 per square foot, this one is selling for $41/sf.

Or has less square footage than what the tax people have.

The house I am renting is not a typical rental it is a 6000 square foot mini-mansion.Thanks for all the replies this thread has been very educational.So if I am getting this right my lease will renew on a month to month and if I or my tenant wishes to terminate the contract then a 30 day written notice would need to be issued.The month to month I am assuming also that the TAR contract and the provisions are what is renewing. 

Also, are there any other small hints or tips or boosting the value if we cannot add on any more square footage to the property?

Now fast forward a bit I have two other big problems one the tenant and I agreed to just calculate the square footage of this sunroom and give her a deduction based on the square footage but it is still an issue with a leaking sunroom of doom. 

I have started to rehab a 1981 Manufactured home in a Senior Park in WA.

Being in WA, I know very little about it. :)

I am a newbie from Washington DC.

On this project, we were able to utilize dead space to add some much-needed square footage.
