No other correspondence prior to the approval email 

I write down the perfect day and then make a list of "themes" that correspond to this journal entry.

That signed waiver corresponds to them getting their last check and only after a walkthrough of the work is done, including sign off on punch list.

It so happened that a couple months after, OCF hit some problems with one of their renovations (see corresponding post from @Engelo regardin how he lost his ***) and we experienced minor delays.

Originally posted by @Russell Brazil:Quick way to ruin your reputation in the market place is throwing out a bunch of random low ball offers that have no correspondence to the value of the property.

So if you do it right and provide quality content you'll receive new correspondence and a new potential relationship for years to come.  

I would also continue to speak directly to the client and copy the agent on all correspondence.

Verifying last 2 years of rental history and income extremely important to find the “best of the worst”.Make sure you understand the Class of properties you are looking at and the corresponding results to expect.

This is because of the next language from USPAP, the Uniform Standards of the Professional Appraisal Practice, which all licensed appraisers performing mortgage appraisals must follow:Standards Rule 1-5When the value opinion to be developed is market value, an appraiser must, if such information is available tothe appraiser in the normal course of business:(a) analyze all agreements of sale, options, and listings of the subject property current as of the effectivedate of the appraisal; and(b) analyze all sales of the subject property that occurred within the three (3) years prior to the effective dateof the appraisal.Comment: See the Comments to Standards Rules 2-2(a)(viii) and 2-2(b)(viii) for corresponding reportingrequirements relating to the availability and relevance of information.USPAP requires the appraiser to "analyze" any current agreement of sale (a pending WB-11 for instance) during the development of the valuation (called the Appraisal in USPAP, different from the Appraisal Report).

Can one limit the communication channels with the hoa to physical correspondence and calls for life /death, real emergencies?
