)  Arizona Arizona is a snow bird state, we have golf, baseball training, then a dead hot summer where nobody comeshow can I come up with some numbers before wasting time to look for furnitures and buying beds ?

Just make sure you are fluid with this info on each property so you do not buy wrong.  

2) You have one rental now, what's your goal of buying more?

We're at the point where we're going to buy an appartment in Dubai. 

Most likely trying to find a sucker to buy this and take over the costly legal battle they are entailed in.So next time someone is like "yeah just get a deed in lieu at closing", think twice about that.Actually, I use the deed in lieu.  

But buying without any inspection is rare.

Multifamily is incredibly complex and if you don't understand the metrics or calculations behind it, you're going to get burned. if you're just plugging numbers in until it "goes green", you are either going to miss out on deals or buy something you shouldn't. 

My personal preference for a buy and hold would be an already established area (or an area that's still gentrifying, but has already seen significant progress). 

I have a lender that will do cash out refinances even if no rehab was done on the property, using the higher appraised value the day after you buy a house.

Most who get tripped up are those buying the smaller multi-families that don't possess the correct use permit/historical rental license activity.
