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?

Obviously I am on here to build a better financial future for myself and paying some one else rent is not a long term goal.  

I am currently also employed full-time as an IT contractor but, eventually, I want to be a real estate investor and landlord to achieve financial independence.

Currently learning, but I look at REI to give me the freedom to do the below things...1) Be Financially free2) Be the best husband and father I can be to my future children by spending as much time with them as I can!

I've secured financing, decided that pursuing a BRRRR deal sits well with our risk tolerance and financial situation, and now we have to find it.While "driving for dollars", Zillow, and networking have landed me a couple leads, I feel as though working with wholesalers will be a huge asset. 

Try Triad Financial, Vanderbilt or 21st Mortgage.

I look forward to making some mutually beneficial contacts and building long term relationships with like minded people seeking financial freedom, abundance and release from the "rat race".

To ensure if I am gone that my family is well taken care of financially.

As suggested, focus on what the rest of the credit report tells you regarding history of collections, accounts 60 and 90 days overdue and just how much of this applicants funds are tied up in financial obligations (car loans, student loans, etc.)

In that case I would not mention offer price without seeing their financials first.
