When I contacted the HOA, they stated that they never received the registration form.Now, I've received May's rent payment, but the tenant has deducted the fee required to retrieve her vehicles from tow.

We retrieve the keys from a lockbox, or a hidden location.

The annual auction in Montgomery county is June and she told me, "The list of properties available after today wouldn't be available until the state retrieves."

When they call in the tow truck they then have to wait for the tow truck to get there and see the whole process through... which makes, a what would be 30 second conversation with their neighbors ....a much faster and pleasant way to handle a simple parking violation and turns it into a 30 to 40 minute ordeal along with the added paperwork and enourmous fines that the homeowner would have to pay to retrieve there vehicle from the impound lot..anyone with critical thinking skills understands this defeats there argument that they dont have time to babysit all the adults in the community...I asked them " if your mother lived below you and her car was getting towed.....you wouldnt let her know that her car is getting towed?"...

I am trying to find their forwarding address so I can notify the ex tenant that the car will be towed if they don't retrieve it.Any bright ideas on how to get this forwarding address?

I started storing digitally on floppy disks and a ZipDrive (i'm in my 60's) but now the drives don't exist to retrieve the data so I printed everything.  

That is usually done in a single visit, with the exception of needing to return for about 5 mins after 48 hrs to retrieve the radon monitor.

Everyone at one point or another has studied Maslow's Hierarchy and knows shelter is right up there at the top, yet this shelter, at least on the Midwest, costs less than an automobile.What I am seeing is we are all sitting in a diamond field and most of the folks in this country are complaining about getting their hands dirty to retrieve those diamonds.

OR are you saying after I buy the property for $40k and spend $2k in closing cost ($42k ALL IN) and it appraises for $65k. 75% of $65k is $48,750 But since I purchased the home for $42,000 - Even though the 75% is $48,750 - I can only take out the $42,000 So basically, depend on the cashflow of the rental to retrieve the rehab costs. 

You could certainly use a rent collector for it, e.g. a friend or family member, but I don't know if I would want someone to do that for me for a variety of reasons, including safety, honesty, path to retrieve, etc.I'd be more concerned about your vacation/relocation and how that would affect your business far beyond your rent receipts.
