Again another problem with Baltimore City is that they have very odd, and strict signage regulations on even the simplest of stuff.

For these properties, HUD regulations define what kind of documents are considered acceptable evidence of citizenship or eligible immigration status and outline the process for collecting and verifying such documents.* These procedures are uniformly applied to every applicant.

You should be raising rents to take advantage of your business environment.

If those are the rules, then those are the rules and I will concede...however, I would have to imagine that a good majority of people perform their renovations directly after acquisition to take advantage of the building being empty and not having to deal with construction in a live/working environment...logical, right...so because I didn't place my newly acquired building in-service prior to demolition/renovations I don't get to claim ~$340K of Partial Disposition deductions???

I’d check the local municipalities website and learn the regulations for specific zoning first and foremost.

For CA to pass it, the Assembly must pass it, the senate must pass it, and the governor must sign it (the governor will sign it if it makes it to him).The rent control regulation to have any value would need to have a law preventing the LL not extending the leases (often mistakenly referred to as evicting).
