Hello Kyle,There are lots of things to consider, and there are lots of different types of Zoning for residential.For example you could be zoned residential, but the minimum lot size could be 1 acre, and you are buying 1 acre, in that case you wouldn't need a developer, you would just need a builder.For example, lets say you have 5 acres and a perfect rectangle property, that has an existing street that runs the long ways of the property so you won't have to put in any streets, you will simply need to get with a surveyor, figure out your minimum lot widths from zoning, and file with the municipality to get your property subdivided into lots.Once you have subdivided lots, you can either sell the lots outright to a builder, the cleanest transaction.Option 2, you could try to partner with a builder so you can split the profits, most builder's will want you to guarantee the loan, and still charge a build fee before profit splits.Option3, you can hire the builder, obtain the financing, and keep all the profits.Option 4, you could do any combination of 1,2, and 3. 

But, you can use it to buy a 2-4 unit (2 unit are much easier then 3 or 4)or house hack a single family meaning live in the house and rent rooms to friend having them pay you mortgage for you.
