I am wondering if anyone has been and this situation and has ideas on how to handle this.

If you ever have a situation where your On Island Agent has to have interaction with your guests, you have to keep in mind this person is representing you. 

The US mainly does recycled steel production since it requires far less energy and potential EPA issues, but recycled steel can't be used in most technical situations.

How does one take the owner finance situation to a bank and turn it into a 30 year loan to hold without an additional down payment of 20 percent ?

You can definitely do a DSCR loan for this situation.

(We discussed the "problem tenant" situation above, and I believe it was an anomaly and not necessarily due to poor tenant screening.)

Given the situation, I would recommend taking the $100,000 from your primary residence.

Sometimes if that is an approval verse a bank account showing $500K for example, the agent on the list side may need a little education on what you are looking to do, I always have the lender call the agent in this situation to get them on board to get the listing agent more on board. 

However, I could use some advice on the best route to take (buy an investment property or a primary residence first).Some background on my current situation:1.
