@Justin Schaefer - I wouldn't consider it a red flag, unless of course you believe that it is somehow not up to code. 

James Bowie “Podio is great, but lots of maintenance/developing. “ Jonathan Ulyatt Pros: “Podio Lite is free up to 5 employee seats, up to 5 external teams”, used by over 400,000 for collaboration, mentioned several times on BP Cons: Need to build projects from scratch, not designed for real estate, CRM that you have to “code” to yourself (according to Lloyd Stanton)“In my experience there aren't a lot of CRM's that do everything.

Andrew Johnson “I use Appfolio out of santa barbara, ca its definitely not free and my property mgmt company passes those costs down to me which I think is around 50-60 bucks a month based on number of units under the service.I am able to see all reports from rent rolls, cash flow statements / trailing 12 month cash flow, tenant ledgers, maintenance requests, dialog between tenants and mgmt staff, resolutions to maintenance requests, move in pictures, move out pictures, or video, and many more features.What I like is that it allows the vendors to be in a dialog/text/chat box so they are prepared (vendor) prior to job assignment with lockbox codes, scope of work and pictures before they even go to the site so we dont waste time figuring things out and run up a huge $$$ bill for lack of efficiency.”

Let me buy and you rent from me :)http://www.cnbc.com/2017/06/23/how-much-housing-prices-have-risen-since-1940.html

@Christopher Collins - In the absence of a clear response here, I'd suggest calling your local code dept or property inspector and asking them what is required as it could vary by locale.We had issues with chimney liners on a property and it ended up being more cost effective to replace the water heater and furnace to more efficient units that could be side vented than to redo the liner (basically cost was the same either way so made way more sense to replace).  

The dress code is the same when you are looking at houses as it is at Casinos or Neiman Marcus. 

While I worked at the IRS for a couple years, I got familiar with the Internal Revenue Code ("IRC").

I think you would benefit more from filtering your list- Location: Only use zip codes interested in areas investing in.. which areas are you looking at specifically? 

And having personal knowledge about how Oregon is pretty intense on enforecing these business and professions codes ..

There is nothing worse than getting stop work order from Code Compliance or losing a sale on a home because you failed to pull a permit.
