People have WAY overstated "cash flow" on BP by ignoring the costs of capex, vacancy and turnovers.My goals in every transaction now are to (1) buy in good neighborhoods, and (2) minimize my outlay of cash. 

Also you would not reduce the price because of the interest payment. that is not how it works.3. yes the note could be sold, but at what type of discount and what if the borrower stopped paying.while there are a lot of posts on seller financing, some estimiate less than 1% of all transaction have seller financing and the ones that do are first position only with an average of 30% down payment - most of these are to people who do not have verifiable income.Thinking you will get conventional financing then seller financing will be uphill battle as the conventional lender most likely will not approve a 2nd mortgage for purchase.not trying to dissuade you, just wanted to provide some key insights so you do not spend 1000 hours chasing something that is impossible to find.

Or because they don't want to be the bad guy.With closing on Dec 4th the issue is that your 28 day notice will be effective Dec 31st and your tenant has until Jan 31st to vacate.

These are unnecessary middlemen that slow down transactions.

If the appraisal came in lower then what was being using originally that could effect the rate/terms.

It seems like a more cost effective way to have multiple tenants. 

What's the most effective means of dealing with this issue?

Its much more cost effective to outsource things like skiptracing and direct mail.

They will confirm to you that the number has been steadily increasing year after year (Covid or recession effects aside).

@Brandon Eike, on an investment property, most lenders will max out their loan at 75% LTV, which doesn't cover transaction costs, which are usually 5%-8% of the purchase price.
