And if you become a repeat customer they may do the same for you. 

If your property is located in the city of Detroit you can transfer the water to the tenant all you need to do is setup your account as a landlord account and you need to deposit $150, then once a new tenant comes in you tell the tenant to sign up as a new customer with the city and the water will be billed to their name and SSN. 

It's a big project (we went the custom route) but I'll operate it as a STR and expect it will gross $4,500/mo or more.While appraisals may not have caught up yet, I think you'll see strong sales prices for properties with ADU's.

So you need to determine who your customer is, what is your value proposition and how you get them over the finish line whether it be online in person or a mix of both

We spent 10 years and then sailed away on a sailboat paid for with tax free dollars, 3 waterfront vacation rentals paying for the sailing, and a custom built dock in the back of one for when we were in town. 

I was just talking on our podcast about this with Anthony Vicino, our tenants are our customers and too many landlords ignore customer satisfaction just because everyone NEEDS housing of some sort.

The business of being a landlord is about providing great customer service.

Where is the highest paying customer?

The challenge arises as the city permits only true divided lite windows, leading to a cost of $40k for 4 custom-built wood arch windows to replace rotted ones facing the street.

I don't think your plans will ever be built my someone else to be honest if they were custom.
