Seller likely does not want to 1031 exchange into another property, wants no management of the property anymore, and wants a somewhat passive income stream from holding the note.If you pay him 15% down that is a large chunk of change.It's different if they are financing close to 100% with 5% down and non-recourse loan.

I work with those who are buying to fix up and flip, as well as those buying to renovate and hold for future rental income streams, or as homes.

Price can also be evaluated from the income stream the property produces.

These resorts have amenities guests love, pools, spas, clubhouses, water slides, mini movie theaters, tiki bars, tennis, beach volleyball, basketball, games arcades, playgrounds and some even have restaurants.

Once the tenant loses that income stream, then they will have difficulties with rent.  

It is definitely not a passive income stream or even close to passive. 

They will take more non conforming loans and lend on the cash stream of the property/ asset. 

The servicer will ACH the fund into your checking account shortly after receipt, zero effort required.3)  Sell to an investor with owner financing, you might get a little less then in scenario 2 but you have two income streams backing the payment, the tenant and then the new owner.  

We are open to occupying one unit of a duplex (to secure a lower interest rate) for example, and have a good friend who would rent a room in our residence - with an extra apartment (or possibly 2 if there is a basement) creating multiple revenue streams to quickly repay a relatively small mortgage.

Here in Canada, both commercial and residential mortgage have terms less than 10yrs ... the most common being 5-years, so "balloons" and renewals are the norm.As Omar indicated your primary concern should be running your business as efficiently as you can and maximizing the revenue stream.
