Specifically, I am looking for a firm with extensive experience in 2nd story home additions.

I have an extensive background in construction for the past 4-5 summers in-between school.

have your real estate attorney ask for an extension.

Once taught on encryption/decryption, symmetries with extensive math application (numerical analysis).You next studies will now be in different entry points in RE deals.

However, it needs extensive work to be considered "updated". 

I am a local Houston wholesaler and I have an extensive buyers list.

I've been looking into this lot for about a year now, simply because I would like to expand my garage as well as build an apartment above the extension to the garage. 

When you filed for an extension, did you request a waiver of the $375 extension fee?  

I have extensive experience with and specialize in preparing real estate investor tax returns and setting up LLCs for real estate investors.

They have been firm on "not taking a hair cut" but you made me think of this from another angle:  It has cash-flowed for them for 10 years and I believe they put in 25% originally, so you're right, they could still break-even despite a lower sale price.
