maximizing available bank funding

[Andrew Hartigan]

I thought I would ask for some general guidance here.  I am on my second live in flip and my wife and I are in the planning phases of whats next.  I own a small business and my wife has a high earning w2 job.  We can get traditional residential loan amount of around 750k.  We like the idea of using all available credit for buy and hold rentals and just renting a cheaper place to focus all available credit on investing and moving in the right direction.  

We should have around 200k for down payments and as mentioned around 750k of bank financing.   We are too low for most multifamily and so I am mainly focusing on 4plex and/ or purchasing multiple sfh.  We would like to take advantage of low rates of Fannie/freddy loans.  My question is the best way to go about this.  I know there is a limit so it may be better to go for higher end sfh homes that still maintain some cashflow or a nicer quadplex.  I am very tempted to dive into commercial multifamily but seems like we would have a hard time qualifying due to lack of experience and being on the bottom of the totem pole in that marketplace.  I basically am just brainstorming my plan for maximizing cashflow but using bank financing as I know most of the high cashflow 40k homes don't qualify.  

Thanks for any feedback.
