I’m hoping to use the information that I learned from that one transaction and the information on BP to find additional deals in the future, while making new relationships along the way.

Do we go to the lawyer first and after contract is signed do due diligence?

I'd expect them to look at my financial situation and assets to gauge my ability to make this type of transaction, don't you think?

I am considering asking the seller's agent to become a transaction broker on the deals I am considering to use as a purchase negotiating tool, e.g. offer less since seller does not have to pay a commission to the buyers agent. 

When we went in to get the keys, all the windows were open, tenant tries and gets us to sign a document saying they get their deposit back in full.

I am busy with transactions in process so have to allocate so much time each day to the process.

foundation work can be expensive, but when repaired properly and defects are corrected I would, sign any limited lifetime warranty, but I refuse to market that way personally....I would rather explain this to my customers why they do that instead of just being honest and say it's marketing and then break it down

Would't be worried about signing the Non-Disclosure.

@Marelyn Valdes   At the time the work was done, he was not licensed for anything at all, nor is there any signed document of any sort.

Their are a lot of homes for sale in those neighborhoods that do not have signs out.
