.: I have a deal in a luxury market where I am looking to renovate a 5,000+ sqft house that is a bit outdated.

Fort Wayne is a good market.

I would say ads are better than cold calling as its inbound vs outbound marketing and most people do not like to be called.

Any insights on rental demand, tenant turnover, or local regulations?

Instead of following trends, tailor your space to the lifestyle of your target market.

Hi Andrew, I pay about 9 or 10 per listing for pricing, and additional 10 per listing for the market dashboard to look at comps. 

This will of course depend on your local tenancy laws as well.

We provide a baked good from a local German bakery.

This yields upwards of 70% more than market.

There are really great REI opportunities in different markets - markets in the Midwest and Southeast of the country are particularly lucrative - where not only are the purchase prices reasonable for most RE investors, but the homes are turnkey (new builds or completely rehabbed homes, tenant ready, systems 10 years of life remaining on them, property management teams in place) with appreciating home value AND appreciating rent.
