I wouldn't limit yourself be deciding that you are going to do single or multi, unless you have an unending supply of good deals in both categories and you are trying to filter through all the great deals you have available. 

And yet, I breathed a sigh of relief...

I have set up filters to send all wholesaler emails to a folder on my email so it doesn't clutter my inbox with other important stuff.

Decide on your strategy.2) If your credit score needs to be improved in order to get Fannie Mae mortgages for buy & hold rentals, then perhaps direct more of your earnings there for a while, but in general you will have more options of you have some cash to work with for downpayments, rehabs, or just some breathing room.  

Before I would waste another breath on this deal.  

I suggest marketing to find properties to use as rentals so you can buy under market value and start out with tons of breathing room. 

Sleep on it, take a breath and listen to those more experienced than both of us.

I look at zillow rents ads for that zip code, filtered by number of bedrooms and sqft within 200 plus or minus. 

I'm not saying that 120K is out of the question, but seems to be the exception to the rule over there where many distressed units can be picked up for under $40k that might have an ARV of $80k to $100k.https://www.redfin.com/neighborhood/1773/MD/Baltimore/Morrell-Park/filter/include=forsale+mlsfsbo+construction+fsbo+sold-6mo,viewport=39.27222:39.26191:-76.64061:-76.66449

With Zillow you can toggle both filters on to view at the same time which is probably an underrated feature.
