I am in Denver and not very familiar with the Charm City market (though been to visit many times many years ago)... wanted to confirm a few things from your report. 

I love real estate.

I do love our old homes - gives the neighborhood it's charm.

Hope to pick up a few more SFRs since I love real estate investing.

If its a middleman or wholesaler they use the time to shop the place around to the ultimate final buyer who will pay the biggest assignment fee.2)    Reasons for not wanting to be last one to sell -    If the individual lots are being developed as opposed to a much larger parcel (like the edith macefield situation) being assembled its probably less of a risk,   but once a large percentage of the housing has been redeveloped to townhouses where I was a couple things started happening - first the feel of the neighborhood changed from charming, historic residential to modern urban,  and a lot of the initial people who moved into the townhouses said they moved there because they like the lower density but could not afford a "real" house.   

I’m not a realtor lover per say, but it is common for newbies to waste everybody’s time talking a good game. ( not saying that was you. )

@Allen Motakef meet ups are a great way to build a network and start a community of people who love real estate 

I bought my first REI in 2012, two cottage homes which I rehabbed into gorgeous, charming spaces and they have never had a vacancy. 

I can also say no to dog owners, even though I’m a dog lover and smoker.

Another thing most BRRR lovers don't consider is that commercial lenders (who you will have no choice but to use eventually if you really want to grow a substantial portfolio) will NOT refinance you after some short period of time at the property's market value if it means you're getting every dollar you invested back.
