Propstream is likely the most popular option you'll hear about for sourcing home owner information and could also help direct you in terms of where to be driving for dollars.

So, you signed up to double taxation of yourself, including the 15.6% self-employment tax. 

I send out direct mail to probate properties so my list is manageable in the range 500 to 800. 

I would like to learn about self-storage investing.

It does not require the seller to pay it, nor does it require the buyer pay it directly.

To add to what others have said, a W9 (which is for contract workers like cleaners and handymen who are NOT your direct employees) gives you the vendor's EIN or SSN and their mailing address. 

I am looking to construct a Self storage facility and I am wondering how much I should pay for land.

Our next step to proceed in this direction would be to hire a civil engineer to do surveying and site map and that engineer would also see if the creek in the back of the property affects build-ability.  

Would love to know what is working for other smaller investors/self-managers!! 

Alright, this is my first time ever posting on a forum of any kind but I figured its a stepping stone in the right direction.
