The physical property just has to appropriately cater to a tenant for a week or so, and repeat business/word of mouth marketing is all about how well kept your property is and how responsive you are to those who inquire about it.

The problem is the owner didn't physically reside on the property.

If you don't have some way to automate the system (or have someone to do it for you), you need to be physically available to make it happen. 

Physically it can be done, but it would neither be safe nor to code.

I'm not saying you should ignore the wellbeing of good tenants - we're all human, I hope!

@Tom Conant I think that it is tough to evaluate real estate with stock metrics for a couple of reasons.1. most people don't buy stocks with loans, which changes the formula2. a large portion of long term stock gains come in the form of dividends which are almost always lower than even mediocre rental property investments as a percentage of asset value3. if there were to be a financial downturn depending on the area there may well be more people looking to rent homes because they can no longer afford to own thereby keeping rent prices more stable. 

I haven’t physically walked through the house but i know from talking to real estate company there will need to be repairs in the vacancy apartment.

A big portion of the vacancy could very well be due to mismanageement (based on exterior appearance, broken down cars and windows, exterior trash etc.) but another huge factor that dramatically hurts the value of this property is the construction going on around it. 

@Luke Massaro, Well it's mid December and there could very well be some changed in the qualification requirements for a sale of your primary/former primary residence that make this whole exercise moot. 

When you say "card or poster", do you mean like a physical mail out or would email be ok?
