Frankly, I'm surprised by all the positive reviews. 

Albany Park surprises me, particularly as to new builds.

I'd be surprised if they can keep their BBB accreditation. 

Tenants in many markets already believe they pay too much (contrary to recent studies that show rent to property values have never been lower for the large US cities).If my insurance costs are not double my current rates over the next couple years, I will be pleasantly surprised.  

The average sales response is pretty quick so I'm surprised you didn't hear back.

The overall LTV (including all 3 mortgages) will be key and your selling point will need to be that the 2nd mortgage ($8k) will burn off in 2.5 years (based on your surprise that it was even out there, I'd recommend that you follow up in 2.5 years and ensure that it's been satisified, so that it doesn't surprise you again in the future).Does the $8k grant vest over the 5 years? 

Using a 401(k) loan reduces your emergency liquidity, which could make the investment riskier if unexpected costs arise.

If an employee calls out sick or quits unexpectedly, you will have to step in to handle the day to day of your business.The amount of work required from you as the owner will depend largely on what services your mat offers.

Surprisingly, these homes that once sold for $7,000 are now selling for close to $1,000,000 and it doesn't seem as though the rate of appreciations is decreasing anytime soon. 

Surprising you can get a heloc on an investment property - those are tough.
