I'm eager to learn about how to find and fund properties that help my family financially and my community with affordable/reasonable dwellings for young families and newlyweds.

I would like to pass on a little bit of useful information for anybody thinking of converting their permit over to owner-builder. 1 - You will not be able to sell the property for a minimum of 365 days from the date of issuing of the CO. 2 - The property must be for the owner's own use and occupancy and not for sale or lease which means you will not be able to rent it out. 3 - The owner-builder must ensure that all employees working on the project have the required licenses.4 - The owner-builder must provide worker's compensation as required by Florida law.5 - To apply for the owner builder permit, you must physical visit the building department.There are others requirements and conditions, however these are the main items.

Does this kind of increase seem reasonable?

For the main house, I'd get a washer and drier. 

I have no reason to stay in Gilbert, other than it's where my family lives currently, so it's nice to be close. 

I believe the main issue is 2 fold: 1.

@Damien Davis There may be a reason you dont see a lot of 4-plexes.

I focus mainly on buying deals and working with partners for said deals. 

How do you determine a reasonable target return?

Last thought (mainly for future readers), you may be talking about the 1 year FHA history if you have variable income.
