I'm currently based out of NH but am willing to work anywhere. 

If you use HELOC, it will have to be in 2nd position, where you can pull up to 90% LTV based on what you own on your current mortgage.

I don't know much about the Columbus market but I'm sure others will chime in shortly.I will say this... judging a market based on what you see for rent on Zillow is generally a mistake.What are you comparing the number of listings to in order to determine it's oversaturated?

The price of the property, and what the bank will finance, will be based on the income the property produces, the Net Operating Income (Gross revenue minus expenses) divided my the Cap rate.

With that said, based on your comment that the income you receive from the S-Corp is not enough to qualify for a traditional mortgage, you may have to consider other ways to acquire the property such as owner financing or lease option. 

I'm looking to form a simple tax strategy based on a very small portfolio, I want to do it right while taking advantage of all the tax advantages that come with REI. 

I am not on Pricelabs yet but looking at the rates for March, they look like what I would expect them to be based on our previous analysis.

Technically, believe you need a real estate brokers license in WI to legally accept compensation for managing a property you don't own.That aside, given the short-term nature of your services, probably be best to do it with a retainer fee and hourly.

Hey Bigger Pockets Family, I am recently transitioning out of a W2 based job to become an MLO full time as it being my part time gig was making me more money most months then my full time job. 

These criteria due to my personal constraints on time (I have a demanding full time job as many of us do) and on connections/team/expertise(I'm not an expert at rehabs nor do I have a team for this yet).So given all of that I am researching on other clever ways of hacking the situation and conditions I'm in to still come out ahed so splitting houses I purchase up into multiple "doors" by renting by the room is a natural conclusion.
