Both have good rental assistance programs now. 

Just keep in mind it is 1 FHA loan per borrower, so you will need to refinance out of it in order to use the program again.Good luck!

There are also tons of awesome down payment assistance programs.

We help our clients negotiate state and local grants, tax abatements,etc.First step is to see what existing programs are out there with money, are you just talking about applying to those or creating your own request?

Last time I checked, the first time homebuyer program was at 85% LTV or a 15% down payment requirement for a 4 family.

Hi for everyone
According to the experience of some of you, I would like to know a little bit more about how the 203k loan works, if you have any link that I can read or something like that I would be glad to get it....

And, even if you find a cheap program, they usually start going up in price as they develop and add more features.There are plenty of way to manage 1 to 3 units that don't require management SW.

There are qualifying life events (like getting married) that let you move out before a year, and many other loop holes in the program which investors can legally utilize.

There are different loan programs that only request 5% or less as a down payment. 

It is not free, but I had success with Kent Clothier's "How to find Cash Buyer's" Program.
