Negotiated for 9 months on one, just waited 4 1/2 months to clean up estate title and today put in another bid on sfh that has been on and off market for 4 years - sale, short-sale, now foreclosure...

I'm partial to the smaller events (like the clean up and Lake Merritt picnic), but that's just my personality.  

I currently hold a note on a property in norfolk virginia that is in foreclosure and vacant and looking to get a property manager or contractor / rehab specialist over there to do property preservation and clean up the property. 

So, I think acquiring both real estate and O&G at the same time is a nice way to diversify cashflow since one favors higher cashflow and performance early but depletes over time, while the other starts slow but will be a rocketship over the long term.  

Often needed between tenant changes or cleanup after a renovation is done.

I'm always terrified of purchasing a house with that history because of the cleanup cost and then the disclosure when selling.

You should look at cash flow over the course of a year, since your water/sewer bills usually come quarterly, and snow plowing is only in the winter and lawn mowing is only in the summer, and leaf cleanup is only in the fall.

Notice the cabinet on the far right.I would rather someone just left it alone so I could do the rehab the correct way then have to clean up someones mess.

However, it can be an effective way to 'clean up' title where fractional or generational interests may cloud the chain. 

Being a good investor you promptly address the issue only to get a bill for 37,050.05 for clean up a month later and an hour later the building inspector shows up and then tags the place for asbestos, it being found during the dope clean up.
