Hey @Mike Nelson, never assume anything about STR rules and regs.Here is the STR rules for Oak Park - https://codelibrary.amlegal.com/codes/oakparkil/latest/oakpa...I would call the city and make sure it is legal for a specific property.Now regarding the famous person angle, sure it can add value to the property or as a STR, but for STR use, I would think you would need it to be in original condition with a lot of the furniture and knick-knacks that were owned by the famous person along with a bunch of photos etc featuring the famous person.If you buy a place that has been totally redone but was owned by someone famous but has no features or things that were theirs, then I don't see it being a draw. 

Most lending is based on cashflow, not the 2% rule (although still a good rule of thumb for some types of investments), might have the most help from the group if you provided some of those details here just so it'd be easier for us to help you best. 

Even in philly in D class area it is tough to hit the 1% rule.

In Columbus, you can still find the 1% rule and there's amazing appreciation potential due to how much population growth, job growth, and companies moving/developing there (recently Anduril just announced another 4,000 jobs coming to Columbus Ohio on top of Intel, Google, Amazon, FB, Nationwide, Ohio State University, etc.).

I have also seen appraisers recognize that multiple ADUs by rule does not qualify for conventional F/f financing.  

Asking in the correct forum will get a better response.Read the RULES!

Depending on where exactly the property is located they may have some different rules/laws in place.

Why they need to inspect the interior when the exterior is pristine remains a mystery, but we don’t make the rules.

Starting out rules of thumb for newbiesThanks for your insights.Hey @Malcolm Brown, welcome to the BP Forum! 

ADU zone expansion is not certain, and even then who knows what the rules will be (owner-occupied requirement, etc).
