A couple things to understand:- Rate is a function of price.

Maintenance/cap ex is primarily a function of unit features and tenant quality and not a function of the rent.  

I have no need for the rent collection or tenant screening as this is a function my property manager does for me. 

Seems good but anyone that actually has functional experience getting deals have some feedback with it? 

All the old, sadly "bad" neighborhoods in cities all over the country are these kinds of homes that we now call "functionally obsolete."

The maintenance/cap ex, not being a function of the rent but a function of the unit and tenant, will consume a significant portion of rent.  

Once you have a shortlist, sign up for an account with each one and test them extensively to see how they function.

I recall a specific framework of business start up along the lines of starting with yourself, then adding an Admin, then an Ops, and then other support functions after that. 

When my accountant was with H&R Block they functioned this way and even though he could prepare my return in about 1.25 hours it would cost me $1800 because of the number of inputs I had specifically from my 7 properties.

Unlike a cash-out refinance, you pay for the funds as you go and it functions as a credit card (rather than a mortgage), giving you more flexibility over the funds secured via your house and is potentially cheaper than a mortgage since it is not amortized.
