The last note was that i learned what a series liability is and was curious if i may be better off doing one of those because i have 2 properties and plan to slowly add more (Maryland does not offer series llc but wyoming does).

Is it legal for me to show the property to the prospective tenants as long as I don't collect commission or sign any paperwork. 

Yes, you should be able to do this, so long as the DTI for the Conventional loan works once the new minimum pmt on the Heloc is factored into your debts.

Why do you think purchase contracts are so long and have such small print?

How long is this going to take to return it?

I currently manage a highly successful short-term rental arbitrage in Houston, boasting over 170 reservations in the last three years.

It's a long shot, but worth asking. 

The last thing you want to do is get someone in there with vouchers that have a definite expiration date, you will see a lot of headache and turnover.

Wondering if these are c/c+/b class neighborhoods and if tenants will be long term tenant and what the vacancy is like in North Linden Ohio.

A couple of Cuban cigars over a scotch can go a long way.
