I like the platform and its user-friendly for both landlord and tenant.

An example is collecting data on online users and than trying to come up with a way to sell them stuff through ads.

I also don't know if you can even use real estate loses to deduct from W-2 income? 

I also know you can contact commanding officers and let them know about issues.  

And I want to provide end-users with homes.

If you can't make the deal work at 130K maybe come up a bit if you think it could command more than 175K ARV, if not then move on and look for another deal. 

Access for Android and Windows users?

Honestly, it's too bad that the operating part of your dad's business does not carry with it some residual value of some sort with regards to that commanding a sale price.My hunch would be that this would be far too risky to embark on as a first go of things.Especially, from what you're mentioning this may have a large impact on the quality of your dad's retirement.If you have the funds and can structure something, the place to start would be to engage with an A/E firm to get a cost estimate generated for a concept building like you're mentioning. 

Thanks for the suggestion on searching for users. 

I'm a pretty new investor myself but if I were to give any thoughts I agree with @Thomas S.I would think Seattle area would command much higher rent than $1600 for 3/2.
