I purchased a property for 137k with a 26k rehab budget and will list for 220k The great news is that based on the circumstances of the property I was able to make 28k in the buy!

You would need to do a walk through as the old tenants move out and document the property condition...

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.

Welcome to this site...This site provides you news and information, real estate information etc.Good Luck!!!!

Also, what kind of documentation should I have readily available considering this will be my first investment loan and I know there a stricter guidelines for these. 

You should be developing strategies to get in front of owners/sellers directly.As far as who these buyers are, this entire year has seen a lot of cash move into real estate:1031's finally able to get a fair price for their relinquished propertiesFlight from the inflated stock marketRace to lock in the fleeting historically low interest ratesPeople seeking tax benefits of real estate not available in other assetsForeigners sick of the abysmal returns on treasury notesThe good news is that very few of these buyers are talking to the owner of the fourplex down the street and establishing a rapport for a property that is not on the market.Good luck.

It's natural for people to forget the exact conversation so make sure it is documented. 

Make sure you document all repairs, inspections, any other conversations that are important.  

In other words there is documentation showing what they say whether it is from the MLS past sales history or reports from a trusted unbiased site like Crompton, RPR.....

When I looked at county recorder web site the 62k was written as 6,234.00 On the original documents.
