I am always puzzled why people allot 10% of rent for maintenance... 

I do have some knowledge of the process of developing land as I work for a commercial general contractor in the area and I’m also a residential real estate agent so I feel like I have many pieces of the overall puzzle but can see the full picture yet.

But does these numbers work or is it one portion of the puzzle?

Also, screening tenants is the most important piece of the puzzle to landlording. 

I'm pretty happy with the property manager I met with this morning, and she's also a realtor, so that's two puzzle pieces down.

I’m a little puzzled because the store has a ten year lease with the current owners, and it pays monthly rent that is about $300 lower than what other similar stores on the block pay.

One of their questions puzzled me.

I guess I am missing a part of the puzzle here.Is there anything that would prevent a short sale on a foreclosed property?

There are just a few puzzle pieces that need be assembled.Analytics are a big part of the game, particularly while working with investors, but at most, that will be half of your job as an agent with the other half being prospecting. 

@Tim Emery - the missing piece to this puzzle is - how much is the 10% down?
