It's better to get a contractor or vendor to give you their for this form which included either thier Soc Sec # or Tax ID number, before they even start work.

As other have said, read the forums, listen to the Podcasts and read the blogs.I would also recommend the local REIA - www.digonline.orgIn fact, this Thurs evening there is a large exhibit being held by the REIA where there will be over 65 vendors including lenders.

If you ever want to trade war stories or exchange thoughts on vendors or come see the project let me know.  

A good contractor is a wealth of information and business / vendor connections that can save you a lot of money.

If a vendor offers campaigns, then this will free you up from having to remember to resubmit your information every time you want to send another letter.  

Even harder to net in the USA if you're a "Vendor not from not the us".

My company is a vendor for that one and most of the subgroups.

Once you pay their entry fee of thousands, to gain all their "knowledge" and "contacts" you find out all the deals they have are horrible deals you could have found yourself on zillow and the contacts ie contractors and vendors again are just a quick list of people you could have found yourself with a quick google search. 

I believe we are going to use a mix of the spreadsheet and quickbooks to keep track of our financials but as for paying contractors and vendors how do you separate each house?

I am sold on the idea, but when I am looking online I am finding places with heavy front end cost, on an unproven vendor.
