@Brendan BeninghofHave a dialogue with the Vendor and make cleaning-up of the discrepancies {at least partially} his/her responsibility.  

After an initial meeting with the vendor, we drafted an offer demonstrating how a slightly lower sale price (8%) combined with a 5-year vendor financing & a capital gains reserve could produce more than twice as much net income as a straight sale at the ask price.Vendor was intrigued, but declined due to a health issue (I had failed to pick-up on this issue earlier and focused on the statements that the vendor was retiring and the property was the retirement funds).We are now submitting a straight purchase (which will take more cash out of pocket for us, but cost less in the long run) at the same price (due to current rent rolls and needed updates, we do not see the asking price as being supported).  

This would be a piece of cake if these 3rd party software vendors could provide a transaction dump into Excel or QBO but they like to pretend like they have a good bookkeeping module.

In addition to the usual networking and vendor opportunities, they will be having a discussion with some local wholesalers.Sign up here.Don't worry if you're not a member - just tell them you a guest of mine & they'll let you for free!

Does anyone have advice for moving from a Vendor Take Back mortgage to a bank?

We provided the quote and uploaded the vendors invoice (which you will see on your statement when the bill post this week) and per your PM agreement, added the maintenance charge on your rental statement.

Being a project manager for a large GC, I assume you have substantial experience dealing with contractors and material vendors.

Check out the vendor forum category to get an idea of who to use and who not to.You can and should also consult with your personal real estate attorney.  

The rest of the house we purchased flooring from an small independent vendor.  

Plenty of great Real Estate investors there to connect with in person, along with vendors, lenders, etc.
