Utility is the number one cash flow killer out there and the unknown you can't control as to how fast it will rise each year.

15 year mortgages are DTI-killers, which can turn into unexpected deal-killers.  

HOWEVER, sometimes pulling the money out and having to plan for the hit at tax time, is still totally worth it depending on what type of RE deal you're planning to do with it. for example, if you're going to do a killer flip long before you have to file your taxes, maybe the profits even after paying the penalties are a no-brainer. i'd suggest partnering with a great cpa that has a lot of real estate investing experience, and having them help you weigh the pros and cons, and see exactly what you have to do to make it worth it. :)

If it is headed towards the property in question you may have a few months or few years until you see killer appreciation. 

I would not consider this a deal killer.

Your rent is under 1%, and those taxes are a cash-flow killer.

Yeah, that's still a good chunk of money but if you evaluate your properties with that in mind and budget for it, it's not typically a deal killer. 

Several are mentioned above.3) Send the new custodian the form to roll the money out of your existing account into the new out.4) Sometime later, maybe a couple of weeks to much longer, depending on the old account holder, the money will appear.Its that first step that's the killer.

HVAC is certainly not a deal killer.

It appears to me that the majority of them are just marketing techniques and they are going to produce a killer deal.
