Since then I have developed my programs and brokrered over 250 deals.

Has anyone had any luck on structuring a deal with seller financing to obtain the land, then use a lender for the horizontal development infrastructure.

Finally, The rent control discourages further development, limiting supply which results in higher rents.So rents go up, but the rent control advocates are too uneducated on the economics of the rent control policy to see their role in the rent increase.Another consequence of rent control is no value in keeping the property as nice.

Although it’s great you have developed great saving habits.    .   

I have bought a couple of units and now working on my own development.

How many units are generally in a townhome development?

As an investor here myself, I can tell you we're seeing solid rental demand here thanks to the strong job market and major employers developing here. 

I have a few lots in New Orleans and am looking to run  profitability analysis of sfr 3/2 development v. one zoned as duplex.  

The first indication is you spent $290k for $1800 cash flow or a 0.62% monthly ratio.Rent $1800 - PITIH $1480 - $180 (pm) - $90 (vacancy at 5% which is lowest i ever allocate in my underwriting and likely low per the OP description of a lot of new development) = $50 for all other expenses.Maintenance/cap ex on 4/2, 2100’ will exceed $300/month even in cheap labor markets on sustaining basis.  

For example, if the property you are buying is a development property, like a small house with a large lot in a developing area, then a small negative cash flow could be okay if you can carry it.
