So how do you address this objection AND make your life easier?

Looking at deeds does not tell you whether a mortgage or other lien exists.To find any mortgages and liens that were recorded on the property, you can search in the County's official records (which for Clermont/Lake County is at https://officialrecords.lakecountyclerk.org/).You want to look for the owner's name(s) and the property address (depending on how you can configure the search) and look specifically for mortgages, liens, and satisfactions as the "instrument type".  

There are so many homes in my neighborhood that are completely falling apart.If you feel the same way, send me the addresses of completely rundown properties, and i'll make a list to take to the city."

They can also target zip codes for hot areas, not just blanketing a zip code and sending to the first 1000 addresses on the list.DON'T expect return on your mailings the first, second, or third time around. 

Then you follow through after X days have passed.You stated that your office "reached out" to the tenant...was this in writing, mailed to their address, hand delivered, or posted on their door?

She sent the RPA to my email address for both me and my husband.

Call the city without giving them an address and ask what the process is to do that.

Given, I'll not have a US mailing address, how will the important communications be addressed?

The intended strategy is buy-and-hold.Below is my plan:1) Using my county's property search tool, pull a list of all 5-20 unit apartments built after 1960.2) Comb through and validate the entries (ensure that mailing address is the owner's rather than the LLC's registered agent's.

If there is, you write the property address down and the executors name and address.
