I run a wholesaling company that markets in the northeast part of FL and I am looking for a new PPL company to buy "motivated" leads from.

If you don't have enough money for a down payment, there is no way you should be buying a home.

I've heard I might need to buy with cash, which confuses me.Could this lead to issues with the closing process, such as problems with deed recording or property assessment?

You would need to ask contractors.You buy something already built and renovate, you get tenants in and start making money that much sooner.

Look up Pace Morby and his groups, etc, they sometimes source homes that don't have as high of an entry fee as buying a home the normal way would. 

My tenant is now living there but needs to use the main house address when buying stuff from companies like Walmart, etc... since the 1/2 ADU address does not show up.

I would look for a multi-plex to buy - up to 4 units would qualify.

I'm in the process of buying land, having a builder build a home for sale on that land, and then selling said home for a profit.If I buy the land in my name, get the construction loan in my name, but I want to sell it under the LLC's name, at what point am I would I report the income under the business's name?

However, I am in escrow to buy a home, but my plan with this one is to rehab and turn it into a midterm rental as my very first buy-and-hold.
