I am active duty military and plan to use the property for deployments/holidays for my family to stay near relatives until I separate in 4 years, then to use that property as one of several future investment properties.

Depends on the actual deal I have seen 85/15 rarely 90/10 but keep in mind your primary home will have a second lien on it typically if your LTV is over 75%. 

I don't think the HOA can restrict what a tenant does within their own unit (the lease can), they can prevent activities in common areas.

I am not sure how active his company Open Door is on BP.

You can still do it...get with an active Broker and hustle your butt off....!

What should I keep in mind to ensure I'm approaching it the right way?

I am actively expanding my STR consulting business!

Thanks to everything I’ve learned from the podcasts, books, and this community, my wife and I currently own:A triplex in MaineA single-family rental in San AntonioA single-family primary residence in Las Cruces, NM, which will become a rental when we move in a few monthsFor context, I’m an active-duty Army officer with about 12 years left until retirement, and my wife works for a university in Boston.

First thing that comes to mind is a mentor but have not had any luck Also I have over 900k in equity across the portfolio, Is there a way to use the properties as collateral for a HELOC across the portfolio instead of individually?
