The best ones I know of currently are:Penfed - up to 80% ltv on rentalAmerica First Credit Union (Utah) - up to 80% ltv on rentalNavy Federal - up to 70% ltv on rental HELOCs are all about the ability to cross-sell you other financial services.

But I ended up living there and utilizing the equity rather than selling it.Now I focus on buy and hold rentals, while aiming for high appreciation/equity growth.

I will disagree that "licensing is easy to get," as the NMLS test is hard to pass AND even if you do, your entity must now begin quarterly and annual reporting to the NMLS System.Also, under Dodd Frank, if the above apply, you are probably required to document the borrower's ability to repay, and service the credit agreements/loans under the strict Dodd Frank loan servicing rules. 

I have a complex financial picture with RRSPs in Canada, RI in Canada, IRA/401k and other stocks/bonds in the US, vacation rental US,.. while I have confidence in my ability I also recognize that there are limits to my knowledge and speed at which I can learn (e.g. tax implications in two countries, ugh!).

Those growth rates can be equal and your NOI will grow at that same growth rate. 

That's several times the growth of the US and Canada year after year.

This, combined with economic factors such as the California exodus (and other migration patterns) lead me to believe there will be long term growth here. 

With that in mind, one of my real estate investor friends is strongly pushing me to build a trailer and/or RV park instead of pursuing SFH’s since I have the ability to build all of the infrastructure myself.So I’m curious as to whether anyone has any advice on the best way to structure an investment like that.

I usually have annual income growth, annual prop. value growth, and annual exp. growth all around 3-5% typically.The purchase price, the repair, and the ARV I am usually being consistent with as well.

So at that time, it was fine even we are losing money or we don't see future growth.
