I thought of just classifying them all as mortgage payments (creating a new type of account), and then at EOY to take the mortgages' statements and retrieve the amount of interest paid, along with prop taxes and insurance paid from escrow accounts.Is there a better way of doing it? 

There should be language in either the contingency form or the VA loan addendum allowing you retrieve your earnest money.

@Roy CleevesSo basically if I’m buying this house in Kingston as a investment property there is no way for me to retrieve first time buyer perks, unless I make it my primary of course.

When I called to pitch my offer of seller financing I was very nervous, but I at least got them to consider, retrieved their email, and said I would email them four different offers/terms, and if they wanted to entertain any of them to reach back out to me.

I have two question for those who's mailed to Tax delinquents as well as able to grab that specific list.I was able to retrieve the list a couple months ago from the county, and it was a total mess I guess they wanted to be really specific of what I wanted since they have millions of records.

In CA it's known as in pro per.Congratulations on you taking the time to physically going to the county court house to retrieve a free list.

They may even charge you to retrieve them from storage if they've already been archived. 

You can also message me directly.To answer your question:I have my real estate agent license so I retrieve CMAs if I have access to the property's MLS (I have access to both GAMLS and FMLS).

I know how you feel when you walk through and look at private items and or personal items.In those cases we just hauled everything to the dump... and got to work. if the old owners are there are in contact of course we accommodated them on retrieving their items.I suspect in this case you would be fine and I personally would not store anything... from the description of circumstances you have laid out.
