There is a web site / affiliate marketing opportunity that my mentor sent me since money begets money (who talks like that?)

I am a senior web developer by trade.

(befor a contractor is being involed)Do you have any app/web/softwer you recomend, or any other tip for quick estimation?

If your interested, PM me and I will give you their web address. 

- it hadn't occurred to me to use a web page format in addition to a more traditional PDF.

@Julie McCoyI have my DVR set to record it.You can also watch past episodes on https://www.homeaway.com/vrp That have a VRP calculator on the web site, not sure how accurate it is.The show is called Vacation Rental Potential Potential.It is similar to Vacation House for free, but they don't rehab a house they find turn key properties, some are already existing VRBO's that someone is selling.

Remember they practice their speeches and make their web copy enticing so that they can sell material.

The web address usually is the street name and something that has to do with the home IE awesomemainstreetcape beautifulbroadwayranchhome It just lists the features and I put pics and sometimes a youtube video.

I got this lead from one of my web pages.

You can also do a inter web search for Note & Deed or Mortgage to see some of the language.
