I will being investing in RE with a partner or different partners. I have pretty much the same idea you have about combining skill sets to improve margins and project management. I have been exploring ideas with a few people that I have met from the SDCIA blog. You might want to visit that site too, if you haven’t.
I have dabbled in RE as a licensee since 98. I am also a General Contractor.I have done both rehabbing of fixers and new construction since the early 1990’s. Based on the description of your skill set/likes and the things you are looking for in a partner I would be glad to talk with you.
