A land contract has been signed in the county between me and my buyer documenting this transaction. 

This is a straightforward and common approach.However, make sure to document the change in the lease renewal or addendum, specifying the new security deposit amount.

Then you'll need to find land, acquire it, find a spec home buyer and set up meetings to design plans or buy a set online with mods.

If I have a capital provider whom wants to be 100% passive and is ready to invest $100k with me (cash), and I have all the syndication structure and offering documents for this project... can’t I just find an accredited investor, present them the deal / get them on board, and go through them?

My advise is to look at property online and see if you can talk with an agent first to see what the rules are for that state.

So, if you don't know how to build financial models, there are some available that are pretty good online (adventures in CRE is a great resource).  

My first piece of advice would be to always be networking with other wholesalers/investors both online and offline.

Has anyone used online lile Zenbusiness?

Either way confront it and document everything 

The model flagged listings that could likely generate more revenue with better descriptions.4.Market Comparison: Using Zillow Zestimate APIs and AirDNA, they compared similar properties in the area and forecasted how much more the property could make if the photos and descriptions were improved.5.Property List: All of this data was organised into a Google Sheet for further review.6.Automating Outreach: They used Claude to generate personalised outreach emails and DMs to homeowners, pitching offers for the properties.The entire process revolves around identifying undervalued homes that look worse online than they actually are.Has anyone seen anything like this?
