It would be nice to obtain some type of return while saving.

I have found a four-plex that I think works out for my cash flow and CoC return desires, but I don't have 25% to put down, and don't know if I would qualify for a conventional loan even if I did. 

Your first mailing should be first class since you get the return mail.

That's close to a 17% annual return. 

and what will it return. 

I have an awesome wife and two awesome girls who keep me focused and driven on getting the ship headed in the right direction.

I would not worry about the loans at less than 4% until you are in a much stronger position.Just remember every time you pay those loans down you get a guaranteed 11.25% return on your money.

I'm just telling you guys if you follow up with people, it will give them a sense of trust when you return.

Will you get a better return adding a fourth bedroom or a second bathroom?

Having people do those things can free you up to focus on what you do best and what gives you the greatest financial return per hour.If you are starting out with very little money then you generally have to look at doing things yourself and boot strapping until you can build enough capital to invest and grow your business.I will give you a case in point.
