Other than institutional lenders turning off the spigots in May of 2007, our single biggest exposure and source of most of our problems was the quality of the property management.  

Cost alone not being my biggest consideration.

The downside is potential turnover that is not as inherent with longterm. 

And because real estate prices have gone up so much and are properties are as unaffordable as they've ever been, there's a high downside risk and the upside is limited.

TENANT:  Oh, I wanted to make it a 2-bedroom apartment.ME:  --Biggest facepalm ever-- You need to contact us before you do any sort of modifications to your apartment.TENANT:  Oh, I didn't know that.ME: My manager will contact you on Monday.Needless to say, she probably won't be staying very long...

so realtor biggest cost is "tech cost" , quite similar to "medical sector".

However, the biggest challenge is dealing with well and septic systems, which can cost $15K - $75K to fix.

We've found it has superior reporting features, integration features, and is overall more efficient to work within than other REI-specific software.The downside is QBO is not set up for REI so you'll need to do that or work with an expert to ensure it is set up for your business appropriately.Something else to keep in mind is your entity structure and how your entities file tax returns.

Basically everything I’m looking for is what’s the biggest bang for my buck.1. 

The biggest huddle finding buyers.
