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.  

If you'd really rather just refi the property, your best bet is to find a traditional lender who doesn't require seasoning (which is typically 6 or 12 months) - not necessarily a hard money lender (which are often non-collateralized loans.)

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

They basically come out the same if you leverage on both sides and then never take additional action.

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?
