First, determine your real estate goals. 

As @Donny Widjaja mentioned, the determination of employee status should not be governed by the purchaser of the materials.  

There are many things to take into consideration when trying to determine if she is a good fit for you. 

Let me start with this:in HUD's Single Family Housing Policy Handbook updated in 2015 it says this: (Straight out of their pdf edition on the website) (i) Time Restriction on Transfers of Title The eligibility of a Property for a Mortgage insured by FHA is determined by the time that has elapsed between the date the seller has acquired title to the Property and the date of execution of the sales contract that will result in the FHA-insured Mortgage.FHA defines the seller’s date of acquisition as the date the seller acquired legal ownership of that Property.

Be sure to determine if it soaked into the sub floor or not, and also if it soaked into baseboard or walls too at perimeter of rooms.

I don't know how to access your specific county's online system, however this is what I suggest you do to get started:1) Unless involving a guardianship for a minor, probate cases of Decedent's estates are public information. 2) Ask to see the Registry of Actions or similarly title list of new cases3) Start with a single case, typically the most recent filing.4) Request to pull the actual file to review5) Review the folder and note the documents and the order in which they are inserted6) Don't even think of separating or removing documents. 7) Determine what data you need, including Decedent's name, case #, PR name and contact info, etc.8) Most researchers capture the data then scrub later.9) If this is too much work, either pay someone else, find a commercial list provider or work another niche.

Your split is determined by MLS agreement, not what's in the purchase agreement, so it doesn't need to be mentioned.
