Welcome to the site @Daryus Cash!

Besides the funding for the subdivisions or site developments, we need funding for the builders to take down lots and build.

To address this, we agreed that I would work in the business for six months to verify the financials, which so far align with his POS system.My main issue is that at 23, I don't have strong financials to get a conventional loan at 75% LTV with a ~7% rate, and the seller's lack of financials complicates bank approval.

Even with all that online bullcrap, I think you could find a mentor of this site to help you and learn more for less. 

Using sites like Zillow, Redfin, and Realtor.com, figuring out deals, and doing your homework well are key steps.

My general understanding of California rentals is that if the building was built prior to 1974 and has 16 units or greater, an on-site property manager is required. 

So far there has been no connection issues with other sites.

Quote from @Nicholas Petrozzi: Nobody can answer that without knowing your finances, your skills, your drive for success, and 82 other factors that can't be discerned from your post.I can tell you that you shouldn't set your bar too high or make things too complicated.

You can literally find answers to all of your questions within the confines of this site.

This is a REI site, and I assumed he was talking about property management after construction also assuming he was building potential rentals.
