You're in EAST CL on Coventry for example, well right down the block is SH, two very different worlds 

Perhaps, your PMC needs a better lease or an addendum to cover issues like this.PMC should send a warning letter that clearly outlines repurcussions of what will happen if the tenant doens't comply.YOU must be prepared for the tenant not paying, requiring eviction and any potential retaliation damage to the property.

In efforts to contact houses that fit our criteria but having issues finding the best service for mailers, post cards, or traditional hand written letters. 

This can be an extremely time-consuming and frustrating process but needs to get done.Borrower Calls – Once the servicer finds your borrower, they’ll make scheduled collection calls notating what transpired and what actions need to be taken.Collection Letters – A variety of collection letters are mailed out based on the delinquency of the borrower.Borrower Statements – Print and mail out monthly borrower statements.Incoming Funds from Borrowers– Any incoming funds from the borrowers will be received, recorded, and distributed to the investor, less the servicer’s fees.Year-End Tax Information – At the end of the year, the servicing company will print out all eligible borrowers who have made interest payments greater than $600.

I know a few people who get calls off letters sure, but its still a vetting process to get to those most motivated. 

Moved out after a year and renting the top floor out, and now repeating the process with another house down the block.

I am thinking about sending a carefully worded certified letter as my first attempt to contact them.  

Just prior to close build a new listing and block existing booking dates. 

You should have gotten a letter to contest the increase.

After doing this twice the HOA management will probably send you a “warning” letter.
