I would like to propose that I raise the rent effective next pay period or they vacate by May 31.

Lots of ways to select location, which one is best depends on your particular area.Beyond those, I also recommend using additional filters to better differentiate your message from competitors sending to all absentee owners as if they were the same.Equity, like above, except separate free & clear from those who have a loan, and use different messages for each group, as their issues and motivations are often different.Age, someone managing rentals in their 70's or 80's is going to have different motivations then someone in their 40's or 50's.Owner location (based on mailing address), a owner that lives far from the property has different issues then someone next door or down the street.LOTS of possibilities, but hopefully that gives you some ideas.

I do not invest my money into anything that I cannot add have an effect on.

Maybe, maybe not, every "crisis" has its own unique causes and effects. 

Look them up on assessor data base and mail letter directly to their home address?

Thanks for any help.First off, if you have a great deal and you’re a hard worker, the money will come quicker than you can spend it.Saving money and being frugal is fine, but least effective and boring for me.

The address is 1725 W International Speedway Blvd, Daytona Beach, FL 32114 on Thursday Aug 30th from 5 to 7 pm.

Is it somehow possible for me to own the in-law if it is on the same lot and at the same address?

I agree, I also thought it wasn't cost effective to jump from one short loan to another just to wait on a better interest rate. 

To address this many states pass laws concerning the sale of a controlling interest in an entity... so while you may think you've avoided paying transfer taxes that is not always true.People also do this to prevent a property from being re-assessed in jurisdictions where a sale would typically trigger that.
