IF it’s that good and successful you would not need a former car salesman pressuring you to buy the course   

Leasing at $3k/month covers your current mortgage comfortably, so refinancing could relieve the pressure of the balloon payment.

I don't want the pressure of a ticking clock every day with high interest.

The doorbell also gets a good view of their faces since it is mounted low, and can see under hats. 

I could sell my entire portfolio of 28 doors and pull the leverage lever OR I could sell this 14 unit and pay for something in all cash and do a lazy 1031 exchange, or do a regular 1031 which puts more pressure on the time frame. 

you say that you "were told to" get an STR for tax purposes, which seems odd, and that you only have 30-40K... and you might use HELOC money to help with the down payment, which will just put tremendous pressure on you to be profitable and support all of the debt.unless i am missing something i would back up and regroup before you buy a random STR in a random market and hope it supports all the debt you will have to have...

For example, if you buy in a semi-rural area or suburban area the pool of applicants can be much smaller and with an increase in supply it creates a downward pressure on prices and higher days on market averages.
