Sounds like you are on the right path in offering services for gaining knowledge.  

I would be careful about bumping the rent to include these services; tenants can get real careless with water consumption if they are essentially getting all they want for a fixed price. 

I would be interested in offering my services as an Interior Designer and/or estimator of rehabs, along with my extensive construction and supply contacts.  

Much of our data/lists actually comes from services that charge monthly fees for downloads, so I am currently not purchasing lists. 

We have a service master guy coming out to give us a scope of work, which may very quickly answer our question.  

Outside of that I have been getting my hands dirty doing maintenance for landlords in New York and New Jersey. 

But don't forget that you have expenses like maintenance, taxes, insurance, heat, hot water, electricity, management, etc. 

The market in the US is more transparent and open here than anywhere else in the world, and there are many services and online tools that will help you operate efficiently from oversea.

Payments are made through the towns lockbox service and those payments never come to her.This fine and dandy however I travelled to the address where the bill is sent and neither of the owners of record live there

I eventually managed to get my maintenance guy down there.
