Improving grading or having downspouts drain into pipes that move the water away from the house often solve the majority of issues. 

You do realize how you got the house right?

The house hacking will pay dividends for a long time I’m sure.

.: Hi,Is there a way to download specific addresses for houses in a certain area online?

You're using a company to manage tenant phone calls/inquiries and then send in vendors for repairs.

A couple tips--Always best to house hack small multis when you are moving around from base to base. 

@Jason Sinclair, having a designer for a wife, I would answer that it really depends heavily on each house, the flow and usability of the spaces as they are, and the overall use of space in the house as a whole.That being said, while there may be a small shift towards more separated spaces, "open concept" is by no means dead, and in many markets, most people seem to still want to have connectivity between their communal spaces.In fact, my wife's current flip is a split level (although technically it is a split-foyer), and she is taking out a structural wall to connect the kitchen, dining and living areas.  

We would also have to close on the house first before being able to open a business account, correct?

We currently own two other duplexes and we've house-hacked all of them.

An example would be a $100k house that rents for $2k/mo.
