One of my life goals is to develop affordable housing.

If you can't put 20% down, you can't afford the property.

There's potentially to create some really interesting architecture, provide affordable housing, and create a great cash flow asset.Does anyone have any experience with this kind of development?

I use onsiteproperty manager.com it is pretty affordable compared to the other ones out there and user friendly. 

(I say this since it's your first flip and assume you haven't done business without a realtor before)Lots of people say they want things, but either can't afford it or change their minds when it comes time to pay up.Don't customize anything to buyer unless you have substantial non-refundable deposit.Timeline - sounds like a big remodel - timelines are hard to make work with a pre-determined buyer.Do you want a buyer walking through your job site all the time?

Buy more affordable houses.

When interest rates are low, if you can afford a high-end car payment, you can probably afford a second home, if you don't go overboard and appearance for your second home in a reasonably priced area.

If we go this route, we'll probably do 7% interest on the land contract.We're working on the numbers now to see if Pat is still interested & can afford monthly payments, and I'm curious about what price we should put on the house especially since we'll benefit from interest.

The problem is that anyone who can afford $2500/month rent can easily afford to buy a $250k house.

South jersey is much more affordable then where I currently live in central jersey.
