That became my dual niche. 

People are leaving California, Washington and other states moving to Arizona per U-Haul's transit tracking. 

Tenants paying rent by Venmo every month, which creates additional work to keep track of it all. 

They know how to track things, use multiple PMS softwares, file aircovers and so much more because I have personally spent years training them exactly how to do things the right way. 

I think people look at real estate the wrong way and want the loss to offset their W-2 income.The first and most benefit goal with real estate is that your cash flow and appreciation is not taxed.if you are making 8% from cash-flow and appreciation and it is not taxed, imagine how quickly your wealth can grow.If you can offset the rental loss with your income income, that is just icing on the cake.

How do you keep track of the days rented and the amount of time you'd need to spend there to make sure you are meeting the requirements? 

I choose to jot-it down on a notebook where I keep track of my expenses. 

In fact, almost all the guests tell me "the photos dont do it justice" when they come stay in the home.

I don't think it is a good idea any more than you should also get your insurance broker's license, your title insurance license, your contractors license, roofer's license, and while you're at it HVAC certification, Electrical and Plumbing Master licenses.Some people do both, but I think for the majority of people there is enough to keep up with on either business that if you try to do both you do neither the justice it deserves.   

We have a line of credit that funds the rehab costs.  1, Form an LLC if you have not already. 2,Track all of your expenses accurately.  3,Talk to a CPA about what you need to track and how (Ex:  new appliances for a home are taxed differently than flooring or paint, insurance, Mileage, disposables, tools, etc.)
