They usually offer more features and a more thorough analysis than online calculators.

They're run by electricity warming up wires and are only suitable for limited spaces as a mostly cosmetic/splash feature under bathroom tile or even just small spaces within bathrooms.

I think areas that will do better are those with attractive features but also have decent internet available to them.

Is your priority to have a ton of features or would you rather have super simple to setup and use so that you can focus on doing deals rather than configuring software?  

My wife is a designer, so likes to put a lot of emphasis on unique finishes and features.  

I have also formatted it such that it will print nicely to form a little report.I have plans to add some features like automatically calculating alternative scenarios for a range on certain values like "rent" or "purchase price".

The most recent home with the same features (SFH, 3 beds and 1 bath, 1008 sqft) sold in that area about a year ago for $33K.

Home offices (or additional bedrooms) will become selling features, as well as finished basements. 

PDF Pro is reasonably priced but doesn't support dynamic stamp.Thanks @Jason Madden Appreciate the response.A few things I've discovered since first posting earlier today.The feature I'm looking for is called dynamic stamp. 

Generally, I would steer clear of rental properties that have too much vintage functional features.
