That way you can add bedrooms, bathrooms, etc. and that adds real value.

Quote from @Jerome Morelos: I recommend converting an existing space, like a detached garage for example, rather than building from the ground up.

The two 4-bedroom units even have two full-size washer and dryers each! 

Generally:Minimum size: Most jurisdictions consider a minimum of 70 square feet of floor space.

This amounts to lost opportunity because if you had purchased RE, at the closing it can start producing return. 5) ADUs detract from the existing structure whether this is privacy, a garage, or just yard space. 6) this is related to number 1, but there are many more buyers looking to purchase homes for their family than there are RE investors looking to purchase small unit count properties.

However, when I reviewed the property information on the PVA website, the records indicate it is a 3-bedroom, 2-bathroom property, excluding the 2 bedrooms and 1 bathroom located downstairs.

Is this a 2 bedroom apartment that is currently being leased (in the eyes of the CHA) as a 1 bedroom apartment?

Especially, is you are just starting your real estate investment journey, a small 2 bedroom 2 bath duplex each side is the best.  

I am a self-entrepreneur and know the importance of office space. 

we are still doing deals in commercial but mostly in the retail/med space.
