I have 100-150K to put towards deals and would hope that my partner would bring an equal value of capital or experience to the table.

You will sign a promise at the closing table to move in, occupy as your primary, and live there for 12 months.

Meaning if it appraises at 575k then a conventional loan will use that as the value it bases the loan off any sale price higher than that would require the buyer to bring cash to the table on top of what ever percentage is required based on the loan type.  

If you are going to pursue no money down financing you need to have a strong case for what you bring to the table and why you will not walk at the first sign of trouble.    

Zip Codes - the best data for zip codes comes from the US Census http://www.census.gov/quickfacts/table  There you can enter a zip code to get a very detailed picture of who lives there, how much money they make etc...Again once you have that data I would do a lot of Google research to see what is happening there.

When figuring out the split, do we take into consideration the amount of money I brought to the table from the loan?  

Not sure if that's what happened, so I apologize if I am wrong.A friend of mine has reached out to me about RE and we still have to work out our strategy on paper and figure out exactly what we both will bring to the table to make this work.

You have to ask want are you bringing to the table?

Half of that goes to the cooperating agent who brings the tenant to the table. 

If you were lending someone money and they had nothing to bring to the table would you give them 100% of the money they needed?
