Yes, mainly looking in the $30k-$100k range (I know anything under $65k is a bigger project).

Quote from @John Williams: I recently bought a home that has an attached dwelling unit where Im planning to move in and rent out the main unit.

While I don't want to focus on doing this as my main source of income (I still mainly want to do fix & flips and contract assignments), I wouldn't mind trying it, just to see if it's something that could work for me.  

There are two main factors that you can use to track gentrification, so why can't they be used to track the reverse?

There are a lot of other issues, but for you as the owner, the main one is usually do you have to have the current tenants out to build (no income) on to the existing property or are you going to do a knockdown new build?

Your deals will always have both Cash Flow and Equity components.3. 

Our house is in the R2 zone (4 blocks off main) and the process to transfer the permit back in March was a breeze.

But that also depends on your down payment- putting only around 20-25% down is hard to have a profitable STVR.Ultimately with STR v LTR, I'd be mainly curious about your intended use of the property. 

What’s your main goal—cash flow, appreciation, or both?

If I was looking in PG County, I think Hyattsville and College Park would be my main targets.
