Development project with slow absorption due to availability

[Bob Bates]

I'm looking at a property that can purchased for a great price due to costs associated with bringing in city services that can be developed into an 80 space mobile park.  After doing some research the cost of adding city services can be eliminated with STC credits that can be collected when the spaces are filled.  This cost along with the site development costs will be financed.  The difficulty comes in the fact that the mobile manufacturers have an approximate backlog of 40 weeks.  What would be the best play on this considering the slow absorption?
