Each bank works differently, so if you carry available credit of say $50,000, but the balance is $0, meaning you've not borrowed anything, it likely won't be a minimum payment on the maximum $50,000 potential debt that'll figure in your DTI, but some percentage of it.

He's going to think about a percentage and get back to me.I was extremely overwhelmed over the weekend looking at new development in Denver, only needing $15k down and a bank statement to hold a unit for 6 months, than potentially sell.

What's percentage should I charge a tentant/buyer for a lease option fee?

Don’t go nuts, just track some of these: web page, blog posts, social page views; click through rates (percentage of visitors who clicked on your CTAs); email bounce rates; sources for leads; social followers and friends.

Percentage or Straight Fee?

Owners pass on the property taxes to the tenants by percentages of the whole, unit repair costs, common area maintenance and full insurance.

If it's a smaller and older garage, I may consider self insuring for that piece and like Rob said, many dwelling fire policies do include a limit of insurance for other structures which is a percentage of the primary dwelling coverage. 

I want to structure the deals so that the investor receives a percentage of the free cash flows generated by each property monthly based on their investment.

State requires 25% overall reduction but exact percentages vary by city.

Short sales and REO sales still happen, but a much smaller percentage of the market share.
