Definitely John,For one, the existing house is in bad condition, I cannot even rent it while I get permits in place.  

Can I pull permits after the fact?  

Are all of the units permitted?

I use a property management company to handle the day-to-day operations and so I only use a simple spreadsheet to keep track of my revenue and expenses month  by month (with a year summary to give my accountant).I can't remember where I found the spreadsheet template (i think i just googled it, but you could easily re-create something like this).Hope it helps!

I have an existing sign so I wouldn't even need to get a permit from the city to put up a sign.Brilliant!

Need help with the most effective and financially savvy method to request a municipal lien search and permit search.Question:When buying a single family home in cash, are there any hidden liens or legal issues  i need to be aware of.

@Mikki Johnson You can go to our local city/county Building dept.s, online to see what permits were pulled. 

Tow that sucker if you are legally permitted and let them pay the impound and then find a way to evict them for screwing with you.

But you can't pay $100,000 for a lot and $30,000 for systems development fees and building permits and build a house that you sell for $140,000.

Towing, minimum housing standards, noise, trash disposal, permitting and code enforcement, environmental issues, the list goes on and on.
