It's true, Banks and Credit Unions will not provide DU's as they are audited much more than brokers and lenders. 

They conduct an energy audit of the building, and then they offer what they can do.

How are you going to deduct mortgage interest, depreciation, property taxes, insurance, etc on the cottage tied to your primary home - without getting flagged for an IRS audit?

We currently use a simplisafe system to monitor the driveway to audit how many guests enter and if they bring pets.

I done retroactive corrections, and my CPA warned that it will invite tax audits.

I'm also hoping to get another property before the end of the year that won't have much time to bring in any income but will need the same outfitting.Going through this with the tax advisor last week, he strongly urged me to consider just carrying the losses forward, if I even had any, since they would be small compared to the cost of an audit and a one-time artifact of the startup processes.  

Any app will require some type of auditing....apps don't know if your trip is for business or personal usage...but they keep up with the milage for you.
