Well, you see, it all goes back to the ancient Greek lunar calendar system.In short, it's "loony".I think they mental shortcut for a "month" being different from a week is easier for regulators to grasp.

Can anyone comment on what the cost would be for slamming 1/4 drywall over ancient plaster walls?

They have been good as tenants, but I'm charging well below market with the agreement that the units are as-is and non-residential.The building is partially renovated, partially demo'd, has ancient plumbing and electrical.

Most are 'ancient' conversions of larger homes and are not very nice.

I'm an engineer by degree so a methodological, data driven approach was important to me.  

However, in recent years, I've seen this used as a methodology of raising money to buy low barrier of entry real estate and make sponsors very wealthy collecting fees while leaving the LP's with nothing but capital calls and suspended distributions.

There's a huge learning curve to buying ancient crapshacks in Philly that have been converted into duplexes.

For example, when I google, I often find those types of "Top 10 cities" without knowing where the data is coming from, what the methodology is, and what parameters are they looking at.

Of course not, and neither do we…but they are a part of the business.The methodology we adopt is that our existing tenants are always a little below market rent.
