In evaluating seller financed notes, there is always a balance between redeeming and non-redeeming factors. 

If the borrower doesn’t pay us every$3.2 million by Jan 15, we file the deeds, and have two offers for the properties in the $3.9 - 4 million range.  

I am looking in the 750k-1.1m range with between 6-10 units.

This gets them thinking about your eventual move and the stress they might face in finding a new tenant.After some time has passed, you could share that you’ve started looking at other homes, but the options in your price range don’t compare to the property you’re living in.

You don't need the huge fridges and ranges untill you get to a higher price point IMO...

A factor is whether the panel and electrical can handle the additional load.

The factors you mentioned are very important to keep in mind for any investment, but I like investing in areas I know. 

You can get solid cash-flowing single families in the 90-120k price range and duplexes in the 130-180k price range.

I do not know San Antonio’s property tax rate but suspect it is in that range. 

It ranges in percentage but nothing has felt different.
