You're paying yourself back interest, the principal is out of the market and not going down, AND you're using the funds to build equity in real estate.

Quote from @Kolby Knickerbocker:  Have you considered building here in Central Oregon or an STR here? 

Hi Matt and all,I’m a transplant (former military as well) with one apartment building in the N Hills and on the hunt for the next one. 

@Monty Alston It has some impact but no lenders will give you credit for having experience building a home unless you have built or renovated a home in the last 3-5 years.

What type of properties are you looking to acquire to build your portfolio, SF, 2-4 MF, or 5+ MF?

It's actually the best strategy in the Nashville area if you can build an HPR yourself and own both, STR the other side. 

Building a strong team is essential for success, and we’re here to help.

Ive been trying for years to use my home equity to start investing in other propeties or apt buildings.

Also any tips for automating this as much as possible and how to protect the property financially and property management would be appreciated.I ALMOST understand the rental arbitrage strategy if building a company scaling with say 30 + units and looking for high short term cash flow.  

That will allow you to build the additional legal space further amplifying the value of the proprety (more HELOC money).
