Initially, I was using Quickbooks (QB) and then when I go a couple more properties and multiple LLCs it was difficult to manage on QB and required multiple QB subscriptions and this got expensive.

Now, some of these answers will depend on what state that property is in, how much equity you have, and a couple of other factors...but you can certainly seek out other lenders about a Line of Credit on an investment property.  

I've only owned a couple sfh am middle-aged and not sure I agree with flipping sfh at this point to create wealth, time freedom and passive income so I have been reading and there seems to be a lot of talk with multi-families and more specifically apartment investing.

Either live in or rent out for a couple of years?

This is helpful and I'll need to do more research into a couple more firms to reduce the costs.

Personally, I'd prefer getting in with the Boston market over Jersey, and would not count of prices dropping drastically anytime soon.

I did shoot you a DM of a couple I think could help you that isn't listed above.

New construction is up, a couple luxury neighborhoods (500k+) and a couple new mid sized apartment complexes (1000+ f/ 1 bedroom).

Would obviously have preferred to use a third party but this accomplishes exactly what I need - a birds eye view of the profitability each month without have to re-enter operational and tenant data into my own system when the property manager is already tracking this information. 

., @Jay Hinrichs and @V.G Jason have done an excellent job of laying out a flaw in your thinking, and I will take it a couple of points further.1.
