@Maria Luna : it sounds like you're off to a pretty good start, since you already have a small portfolio.
If cash-flow is truly your goal, then you may consider shifting your portfolio out of appreciation (i.e. low/no cashflow) markets like SF. I'm guessing if you took the 200K out of the SF property, you'd be cashflow negative on that property? If so, you would have to make additional cashflow in your out of state properties to make up the difference on top of your 5K goal.
Further, taking out a $200K HELOC would effect your debt-to-income ratio (DTI), which may disqualify you from the additional debt you need to purchase your new properties, unless you can get non-recourse debt. You'll have to do the math or ask a mortgage broker.
But let's say my assumption is incorrect and that you could tap the full $200K equity at cash-flow neutral and DTI isn't a problem. That gives you a capital base of $350K for your new projects. 5K/month is 60K/year, which amounts to an annualized 17% return. That's doable, but a bit on the aggressive side, given that you'll also need reserves and you won't yet have much economies of scale.
So, I wouldn't plan on being able to do both projects in one shot. More likely, you'll have to snow-ball. That is, buy a value-add property, rehab it, and then do a cash-out refi to start your next project (BRRR as everyone around here likes to say.) :)
Just make sure to have adequate reserves AND a plan-B in case there is a downturn in the economy!
Another idea is to invest the full $350K passively, which may get you close to what you need depending on the operator. A discussion of the pros/cons of active vs. passive is beyond the scope of your question, though.
Yet another idea is to start a syndication yourself, which would allow others to invest in your deals along with your own money, giving you way more leverage.
Hope that helps!
