Not sure if we have any regulars on the board with event venue spaces.

@Sean Franklin call the local board of realtors office and ask if they would allow you to email their members.

Discipline is key if your using this method. 

Hopefully, you already asked to see the following items:- lease agreements (look for: special maintenance clauses and what items the tenant is responsible for repairing if any, late fee dues and dates, security and extra deposits, what the owner pays vs what the tenant pays for utilities, landscaping, pest control, etc)- payment ledger- notices given (if any)- copies of annual inspection reports- Estoppel Certificates (show rent, amount of security deposit) if you do not have an agreementYou will need the current property management company to also provide you with current tenant contact information, keys to the unit, and any paperwork listed above.

The reason I ask is, what if you started non-renewing the Sec 8....granted you lose that "guaranteed rent" (heh, ask me about THAT sometime), but if you can get it up to market rent gradually while reducing expenses, this deal may still work.3) Cash flow & NOI are key components that determine the market value of multi-unit/commercial property. 

After installing the cement boards and taping them and all that jazz I ended up using a waterproofing membrane which was considered optional. 

Is there a board that discusses the different types of real estate investing?

My plumber disagrees and says I should be proactive and do the fix to prevent a larger issue in the future.Thoughts on if this is the condo board's responsibility and whether I should cover the costs for the fix?

It's not your tax files where you might clean them out after 10 years, they cannot be cleared out.If the HOA is out of compliance I would not buy into the unit and if there and they don't comply with your legitimate requests you'll likely have to sue them.BTW, I used to own a lot of property in Houston TX which has no zoning so everything was in an HOA, I've served on HOA boards and been president of HOAs twice including my current residence in CO.

I am not 100% on board yet,  I have more research to do.
