HELOC can free up the additional 10-15%, but comes with a price (fees, higher rate, higher risk).It may take a while to save another down payment on annual positive cash flow from 1 property, depending on your numbers.

There are a few additional research tools that I use that may not be as well know that I thought I'd share. 

@Ryan Wright  When banks calculate your DTI ratio, they include the additional debt you will be taking on.  

Our buy and hold strategy is purely for income supplementation and to leverage into additional buy and hold strategies.

I recently compared the numbers for the no/negative appreciation style markets with the no appreciation but good cash flow markets.

In addition to the tools listed, I use Google maps to also learn an area. 

Create additional columns to the right of your leads with your mailing dates as the headings.  

Have any of you experienced this and know of an effective way to prevent the additional waste?
