I am a real estate investor who specializes in developing and
financing mobile home lots. No payroll, No employees. For help I use
only subcontractors. For bookkeeping should I use Quicken or
Quickbooks? Why? Thx.

Dear Lucyfur,

If you're in business, then pick the tool that's designed for business. 
Even the lowest level of QuickBooks is better for running a business
than Quicken. Quicken is really a personal finanial management tool.
And it's really good for that purpose. 

Yes, I know. Lots of people use it for their businesses. And they've
adapted sophisticated charts of accounts to make that work for them. 

But, for business purposes, the reports are hokey. The terminology
is all wrong. So, when your banker asks you for a report, Quicken
calls it something else. 

QuickBooks will give you a double-entry set of books, painlessly.
You'll be able to get proper Profit and Loss Statements, Balance
Sheets, General Ledgers. And more. 

For the few dollars difference in price - go for the business tool. 

This is coming from someone who has been working with both tools
since they were in DOS form. (And I have at least 3-8 versions of
each on my computers...to accomodate different clients.)

Best wishes,

Your TaxMama-ga

Great answer. Just what I was looking for.
