question contracting 1st seller finance, on straight forward deal

[Matt Berklacy]

I hv no real life experience with this exact transaction as buyer,, so appreciate your insight for action..

- I'm sitting at kitchen table with seller.

- I have a 2 page investor friendly contract, and prepared to use expensive hard money cash as-is.

- seller is suddenly willing, and wants to finance deal, X$ a month for 6 months or more, balloon at end of 1 year max or less to pay off.,

- Buyer is Virginia LLC , there is full disclosure of everything

- Florida property, Jacksonville Fl..

- seller balance owed 63k, titled in seller name, being rented out to family who are leaving in a month, (tmi; repairs light 22k, arv 195k, rents $1350, purchase price 120k

- possible hold to rent or Exit as flip.., ..to pay off balance,

 my Question is on paperwork and pivoting..:

- Can I contract this on the spot at kitchen table with same purchase/sale contract financing showing cash, get it done,  and then get an addendum with financing terms signed and give to closing attorney?

- Can I avoid setting up land contract right now and get this done straight forward as is.

- does she, being rental owner have to vet llc buyer? if so how?

(THX!!   really appreciate your experience and suggestion..im super interested in S.F in general but want to apply it here and also not lose it .. , and  want to get this done as hassle free and straight forward as possible)
