Just curious, does anyone know/remember roughly what price adjustment percentage the DFW market experienced as a correction during the aftermath of the financial crisis and into the Great Recession?

The fewer units you own the bigger percentage you will have with any occupation. 

or does that negate         the 50/50 percentage and somehow count as self employment income, employee, manager instead of member managed, etc.?     

Look at the potential net profits in both of your strategies and compare them on a percentage basis. 

I was looking for a good sized city--at least 60k, not too much crime, reasonably low vacancy rates in the area, but fairly high rental rates (percentage of folks who rent). 

What is the percentage of credit to debt that is acceptable? 

It will depend on the person's personality how the conversation goes from there.Engineers and IT people like the numbers that they can make percentages and ratios.

Could I possibly get some ideas of alternative options for down payment percentages or alternative funding?

My new PM wants to charge a fee if their is work to be done, i agreed to that but said i am not responsible for the fee, that it can come from the security deposit, but only after i am reimbursed for my expenses first, then whatever is left they can take their percentage from.Yelp i do not pay too much attention too as @Al D. mentions.

One way to do it is to keep meticulous records of who paid what then at the end (the breakup, if that were to occur) take the percentage of who put what in and add that to the 50% that both of you started out with when you signed the tenants in common (TIC) contract.
