@Jesse Li  these rules were spawned out of the POST GFC  08 to 2011 melt down.. in those days in many areas including FLA you could easily find those properties.

If you get a trip, it means your load on the wire is more than what it is rated to carry, increasing the breaker will just overload the wire (since it will not trip anymore), and an overloaded wire will heat up, melt, cause fire.

Right off the bat I know concrete will be more expensive but will require less maintenance and Asphalt will be cheaper and may help melt snow in winter but require resealing every couple of years.

That tenants making $80,000 a year with an 800 credit score are still capable of melting the vinyl siding off the building with their grill...

We have melting snow today - good grief.People have said KC is a great market for investors and having lived there for a few years, I can certainly see why people think that.

If you have to solder a copper fitting, though, you can't have any leakage at the point where you're soldering or you'll never get the fitting hot enough to melt solder.

@Hattie DizmondCompared to the rest of the country, DFW RE market was definitely Crashproof in the last real estate melt down. 

The giveaways are the age of the roof (that may be included in the MLS listing and, if not, the County or City building dept should have the previous roofing permit on file so you can find the age that way), leaks anywhere inside the house, wear and tear, melting or warped end caps (the pieces that wrap around the edges on comp roofs), missing shingles and eave damage.

Hi Chris,Step 1 (if you have not already done this) is to get your 80% lined up and ready to go.Easiest way to do this is to talk to a commercial loan broker (but they charge a point or so per X of the loan) in cash, but may have access to tons more 80% lenders than you do locally.The other way to do this and save the points in your pockets is to start treking into banks (vs calling them) that offer multi-family loans of the size you want and talking to them about their requirements for the loan (or if you want melt down your cellular calling them).Tell them what you want to buy and they will tell you what they require, (different banks may have different requirements)--then line yourself up to meet those requirements.If you think you will do this with 100% Zero out of pocket--that is a long shot--the correct amount of cash greases the wheels--so if this zero down plan is not working fast enough, maybe get a second job and save up the required money---move back in with your parents, eat PB & J 3 meals a day, etc...Good Luck!

But the risk of a real estate market melt down is haunting me.
