Now I'm incorporating business into it. 

I really want to find out the best form to go into business as I would like to incorporate and apply business credit.

That should allow you to pull that furnace and reposition it and incorporate other "used" materials.

Thanks.Some of those incorporate fear of loss too.I know I analyzing it alot, but last time I sent out quite a few postcards and got some calls, but nothing panned out too much.

In CA for example, a BROKER can incorporate, agents cannot, and neither brokers nor agents can operate as LLCs.You just need good E&O insurance that covers property management (not all policies do).

Because of your building skills, it might makes sense to keep doing that, and incorporate your up and coming investing knowledge.

But using two seperate contracts always works and using a contract that incorporates a lease and an option only in limited situations simply is nothing more than a seperate product to be marketed, it serves no unique function that would not be accomplished with two agreements.You need to begin at the beginning to understand concepts used to buy, use or control a property.

An estoppel letter is typically used in a transfer or conveyance of real property before the Closing transaction.It is a document sent to a bank (or other lender), from a homeowners' association (or condo association), to a city/municipality, or a tenant requesting a payoff of a mortgage, assessments or taxes due, or rental amounts due on a lease, to incorporate these amounts into the Settlement Statement for the buyer and seller of the real estate.

Some operate under a single LLC, others create an LLC for each property, while others incorporate and create individual LLC's or Divisions for each property within their corporation. 

Is there any questions or things you have done that you wish you knew before incorporating?
