I've got a property under contractPurchase price $78K out the door (I have cash to close) Intent: build on the property which already has a functioning well, septic, and needs PGE installed Total buildout on the prope...

That would be a situation where you have a joint brokerage account with a family member(brotheror sister, etc) or for example you own a piece of real estate with another party.

To protect our rights, we would definitely deliver a formal 5 day notice (Wisconsin Legal Blank), but at the same time indicate that we are looking to collaborate to find a solution.

One last piece of advice—don’t rush.

Make those connections first.I know you want to take advantage of a great opportunity in your lending terms but that's only a piece of the pie when it comes to success in real estate.  

Is in there, but a great thing you can do now is get your "core 4" figured out - agent/lender/manager/contractor - obviously you can adjust this and do one of the pieces yourself (self-manage for example) or don't need a contractor if you do only turnkey etc but getting this nailed down early is key

One piece of advice I often repeat is that the goal of diversification is to reduce or eliminate any single point of failure.  

start with one piece of land for one single family or a smaller development. or get the buy box of larger developers. why would they need to partner with you when they can do it on their own or find someone more experienced?

That will be an important piece to this depending on how you plan to source your capital.

You also want to think–and this is perhaps the most important piece–how will this particular laundromat fit into your life?
