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.

Also, there are only three legally acceptable ways to serve the notice:Personal service - Personally handing the notice to the tenant.Substituted service on another person - The person serving the notice must leave the notice with a person of "suitable age and discretion" at the tenant's home or work and also mail a copy of the notice to the tenant at their home address.Posting and mailing - Taping or tacking a copy of the notice to the rental unit in a conspicuous place (such as the front door of the rental unit) and also mail another copy to the tenant at the rental unit's address.

But a suggestion - maybe investor carrot should take the time to learn where things went wrong and address those for future customers?

In order to refinance a home as your primary you need to prove residency by supplying a Drivers License with that address, Paystubs must also show that address, tax returns must show address in additon to the mortgage statement is it mailed to you or to that address. 

Keep your real estate sales business completely separate from your real estate investing business.....probably everything should be compartmentalized....separate bank accounts, separate addresses, etc....your CPA and attorney can advise on when to create LLCs.A couple of things about LLCs attorneys have told me....#1 It is really tough for most people to keep things separate and follow LLC rules.
