Don’t risk inheriting the seller’s errors and/or headaches.Whether your new purchase is meant to be owner occupied or an investment property, demand vacant possession or walk away.

Explain to them that if they sell, they likely will have substantial tax consequences but if you inherit the properties, they are "stepped up" on the tax basis.

Important to this discussion is that there was some commercial property my grandpa owned, which my dad then inherited, which in turn my brother and I inherited.

Tenants are inherited- been there 10 years . 

I inherited tenants on a new property and have a couple tenants who have not provided this after following up a couple times, so I can't set up the bank accounts.

I will be inheriting 3 tenants who will be on there current lease for the next 9 months.

Am I able to bill an inherited tenant for damaged incurred in the unit? 

Transferring to an LLC is not seen as estate planning or an inheritance event.Most say it doesn't happen, but I see that quite probable in a climate of raising interest rates (why wouldn't the bank prefer to redeploy a loan made at 4% to current market of 6%, let's say) and/or if you are further along in your amortization (the bulk of interest is gathered in the first years of the loan...so if the bank got most of their interest and now have a reason to recall the rest of the loan, what stops them from trying). 

Also, as the weather warms, hopefully the a/c is on the thermostat - showing the home with the windows closed should lessen the impact of Hampden.

Inheriting a PM where possible might be the best.
