I am in position to pay off with cash with some help from home equity line of credit  or pay off totally with cash and use home equity line of credit for any emergency cash needs for a year to replenish my reserves Need advice to make better decision I am not in rental or real estate business .

Congratz on your decision to make a move.

It's a calculated decision based on at what stage and condition the building is in.For retail if there are no demising walls yet and it's in a cold dark exterior shell condition the all in costs for putting in walls could be 35 to 40 per sq ft with plumbing and ceilings etc.If you have demising walls already could drop to 25 to 30 a sq ft.

Is there anything else I should be asking for before I make a decision?

You must ask yourself, once you figure out who you're partnering with, do I trust these people to make sound business decisions?

Robert, I wanted to add to the other helpful replies...Make sure that you commit to YOUR way instead of having deals dictate what you do in which cases can confuse you and cause you to make bad decisions.

So it's still not an easy decision.  

Would love to hear thoughts supporting or not supporting my buying decision. 

For my house, my property manager lets me know the details of the animal, breed,  sex, and size, then I make the decision whether or not to rent to them.I think the bigger issue is the integrity of the tenants.

You are often able to speak with the decision makers (underwriters) as opposed to working with BofA for example where you are just a number.
