Miki,I've never done a HELOC on an investment property but I've completed numerous successful cash-out refinances, so I second @John Warren - refinance. 

--If you can afford to go straight into multifamily, the economies of scale in this category make it much easier to generate initial cash flow.

We did have numerous tenants actually buy houses and give notice this summer.

You get same rate, expert advice and service, and someone who’s advice you can rely on as you continue to expand your portfolio and need advanced mortgage planning strategy.Unless you like being bombarded by numerous unwanted solicitations, having your credit pulled 3,4,5+ times (Mortgage broker pulls it once and shops for you), and working with a call-center internet service rep who just got their license a few months prior and has 0 time to coach/guide you.

I’m in the Navy and will be going on numerous underways along with deployment almost all of next year.

I will be careful to list any age, gender or any other categories under fair housing rule.

I have a notebook with all the categories for my expenses that I need for my taxes (rent, insurance, property taxes, repairs, etc) and keep track of each property in that book. 

scope the pipe, find the leak via camera, mark the floor, repair the leak directly under the slab, keep the rest of pipebust the hole up yourself or with labor to expose the broken pipe then pay a plumber to do the repair, you back fill the hole with dirt and do the concrete patch, you do the flooring repairI've done this numerous times.

Each one of those asset classes is tied to a phase of the economy (prosperity, recession, deflation, and inflation), and the idea behind the portfolio is that at least one of those categories will be performing well at any given time regardless of what's happening in the economy.
