We are just wrapping up on the rehab and plan to rent it out in about a month.  

I looked at GPS tracking, but they need batteries changed frequently, and a monthly fee to be paid like a cell phone bill, any ideas would be greatly appreciated.

For example, if they are only using it 6 months of the year, maybe account for it being rented 50% of the time they are not using it, so about 3 months of the year.

You would put up a down payment and the rate wouldn't be as good, but it would only be for a few months until the project was completed, then you could re-fi with the VA 100% LTV benefit with a better rate, and you probably would be getting more cash back then you put in, assuming the property value appreciated more than the costs of the renovation.This would also mean you could get more bids to actually compare with and pick the best one.  

I also have a local bookkeeper, QBO, Bill.com & generate owner statements in OwnerRez.We currently have 23 properties under management and am utilizing trust accounting to the best of my abilities (although we are not required to in our state) but everything is really inefficient when it comes time to do monthly reconciliation and distributions.

Zillow says it may go for $289k +/-My current tenants are using it for business and pay $2,250 a month.

We're almost at the finish line but we've been "almost done" for the last 3 months.

I work 6-7 days, but we also go on vacation every 2 months (thanks Tim Ferriss).

I see them as a high maintenance item that will not be as popular as you think they might.I would do a hot tub first if that could work.EDIT - So I just chatted with my neighbor and he spends about a 2 hours a month keeping his sauna in shape.

I would bet they are spending 5-6 figures a month on facebook and other marketing.b.
