Follow Bob's lead because when a guy spends most of his working life as a professional property appraiser as he did, from what I know of him, you would be wise to acknowledge that he understands market cycles.

I am sort of known for this area because I started talking about how to navigate these differences, and just actually acknowledging these differences exist and how to adapt to them to obtain a good income generator.

So far I have paid him in checks or some material from home depot.Is it enough to write down all payments/material provided to the contractor and have him sign and acknowledge that all this is received?

If its homepath and 100% EMD the one thing I will watch for is to make sure you do your inspection and due diligence within the alloted time.Last time I had a homepath deal, my first one, I got a verbal counter from FNMA, the LA was late to inform me, then the back and forth on the price several rounds, and I didn't know then when FNMA counters that very day, was the "acknowledgment date" and I had 10 days from that day to do my inspection.

I acknowledge I have much to learn. 

@Kevin Levesque ,I acknowledge that there is a continuum of beliefs on everything from zero debt to 100% leverage.

When you move in, the HML's "coaching" was verbal so a court will not acknowledge it because it's your word against his, but your lie was in writing before a neutral 3rd party notary public, so it was 'real.'

The law requires tenants to be given the booklet about lead paint safety which is available on the pine tree legal website and then the signed acknowledgment letter is kept in their files. 

This is not an active deal just theory, but seller disclosure and acknowledgement would be provided in this example.

I DO NOT advise landlords or management companies to bake in a sentence into the lease stating, "tenant acknowledges consideration in reduced monthly rent amount for maintenance services."
