Cost effectiveness? 

We will then, as the units turn over, get rents up a good bit further with additional design improvement renovations and hopefully reno into lower interest rates when they drop or at the very least in 5 years on our 20 year we'll have paid off enough to refi into a smaller loan.That is the only kind of smaller deal we can find in neighborhoods where we want to buy now. 

Being able to purchase a property with only 5% down means you can leverage your money way more effectively.

The one big caution I would have for investors on the design is don’t make the room size too small.

Hi BP community!  I currently House Hack in Everett, WA (near Seattle) and utilize FurnishedFinder for our basement ADU with great success. I have built up enough equity and savings and will start adding multiple rent...

If you can come in and operate effectively I think you'll find success rather quickly due to that.BTW - for a property management platform I would highly recommend Buildium.

I would need to consult tax consultant for this however I expect to reduce my effective costs by ~$1,495/month (based on a 32% tax bracket).2.

We also team up with great interior designers who can boost revenue too.

I think that if you are serious about doing your accounting and taxes efficiently and effectively for your business, your best bet I would say is a CPA that specializes in accounting and taxes for Real Estate Investors.
