If I want to instead make it so that my parents' names are exclusively on the mortgage (without mine), I'm wondering if a sale is the only way to go (the loan is not assumable) or if it's feasible to refinance to get their names onto the mortgage with me, then refinance again to get my name off of it in a year or two. 

If you desire to get it by all means go for it - knowledge is power - but thats knowledge you pay for that may or may not pay off for you.  

If you are trying to go for 4 or 5 people I would stop and consider if a general theme for the home would work so that the people living there have at least something in common. 

Of course if rates go down, you should be good, if they go up, then have them rerun your payment amounts and purchase power so that you're good to go there.#3.

We fee like a conservative approach will let us go through the growing pains of better understanding real estate investing without the worry of being over leveraged to add to the stress while we are both still employed full time in our careers and do not plan on quitting our jobs to go fully into real estate. 

I suppose what I’m trying to figure out is: if my property is 1.5 - 2 miles (30+ min walk) from the closest cluster of hospitals, how much will that impact the units desirability for most nurses?

They tend to go out quickly and rarely look as good. 

I am happy to assist and have a detailed discussion to go over potential options to help if you would be open to it.

You may find a good deal in any neighborhood but some more neighborhoods are more desirable than others.

An option for you could be to go with a DSCR loan with a reduced prepayment penalty period so that you can get funds soon and if you want to refinance next year or the following due to lower rates or wanting more LTV than you're able to do so.You should look at this one with the mindset of:1) What would my expenses be once I refi vs what they are now?
