The Management Company is recommending at this point, because there is a dispute, to send some kind of bill showing that this work was done and if not, it would be best to issue a refund.

Go to local title companies that are owned by attorneys.

My tenant, who received the company check, addressed to our company, was able to cash/deposit it at their big name bank.

You would want to work closely with your CPA or a good 1031 company to nail down the timing of it all. 

But my calculation reports show that as the years go on, the return rate growth is rapid, at the same time that equity buildup is the same..specifically after year 10.

I have been investing in SFRs for the last 16 years and I have built a turnkey company from the ground up starting in 2013. 

I think I would look for a company that has an architect and construction so that just maybe things are a little more streamlined.

If not, I would still recommend going ahead with a professional cleaning company that has experience with mold remediation (make sure they send before and after pictures as well), if you really wanted you could give a small credit to the tenant to make them happy as well but 100% not required. 

Are there any specific marketing channels or tactics that property management companies often overlook but can be highly effective in lead generation?

@Brianna Johnson you’ll need to find out from your mortgage company how much extra you can pay into an escrow account because many have overage triggers where they’ll send it back to you if it goes over their limits.
