The good ones will only give you the leads with real estate, address of the real estate, mortgage balance or guessed equity, attorney name, phone, address, maybe the executor /administrator name and address and maybe some other info in an excel/google doc so you can sort/shift the data to attack the ones you want to go after.   

My question is how would you attack this situation for tax advantages and rental income.

When you are ready to attack your next rental, we'll be rooting for you!!    

Keep in mind, your assets can be factored in and attacked in court and you could end up with a lien if you do not have endless cash to pay.

I recently had a tenant that always pays early and this past month they paid almost late, I reached out to her early and turned out she was in the hospital recovering from a heart attack.

In my case, it seemed to help but do ask your lender.I know of an investor that actually filed a mechanics lien on their own property to protect their "loan" incase a legal attack would get too costly for the LLC to remain.

Attack the things you're not comfortable with.

For example,  What happens if he has a heart attack or a car wreck and is injured or dies? 

Come up with a plan of attack before you buy the house. 

@Cory Ellegood Everyone has their own plan and way to attack the problem.
