I have been looking into the unsecured lines of credit as a good option for me. 

@Pamela Smith Did they offer a full refund if not satisfied before you bought into the program?

As far as we know we cannot 1031 into another country?

When something goes wrong or breaks a tenant will just let it be due to past bad experience with repairs/fixes not being done at all or just a bandaged to a bigger problem. 

I don't want to get into a scenario where I have 6 STRs and have to text and Venmo all of them. 

I'm definitely looking into their current fund.

This is a single family home and was originally a primary residence before turning it into an long-term rental.Some strategies I'm considering to grow my portfolio are using a HELOC/1039 tax exchange to purchase a second investment property/multi-family property or refinancing my current investment property into a conventional loan to utilize another FHA loan for a primary residence (with the idea of eventually turning that into another long-term rental).I currently have a 7% interest rate, and am considering refinancing in the coming months if/when the rates drop.

I have been looking into the lakes area of NH so far. 

I know there are many great tax breaks too from my listening to the BP podcast so I presume that owning property in a company is the best way forward in the USA, much like it is in Europe, is this true and if so, what company structure is best please? 

If that is accurate, I'd suggest you invest that money into education.
