After a certain number of calls to the same property within an annual period, the city starts charging my company per call (~$250/call).

Imagine having to create a page for every city you want to rank for. 

Some local jurisdictions have harsher rent control and it can cost more in those jurisdictions.good luck  If it is in the city of Los Angeles, most MFU are subject to rent control.

I just purchased a 2nd home, within a few miles of our other 2nd home in the same city/county. 

One house to another, with all else being equal, the rehab could be exactly the same and the purchase price as well as the exit value could be largely impacted by location/school ratings of that location. 100%, IMO to many focus on schools, how close to the city, crime ect.

Quote from @Jackson Ebersole: Hi Piper,It's always smart to flip properties in-state, and I'd like to share some updated insights on why this approach is beneficial, especially in the New Jersey area.Lenders typically feel more comfortable with in-state flips because:You can manage the rehab more easilyYou have better knowledge of local real estate trends and valuesYou can respond quickly to issues or make decisions fasterThere's a lower risk of fraud or being taken advantage of by distant partnersI can help you with recommendations for the New Jersey market:North Bergen: Continues to show strong potential, with average profits now around $150,000 per flip and a gross ROI of 85%.Willingboro: While specific flip numbers aren't available, the market remains active with a gross ROI now averaging around 130%.Gloucester City: Still a top performer, with gross ROI hovering around 180-190%, though still on smaller profit margins.Irvington: Home values have continued to rise, with a 20% increase over the past two years.East Orange: Has seen steady growth, with home values up by about 16% since 2022.Paterson: Experienced a 14% increase in home values over the last two years.Additionally, Jersey City and Newark have emerged as promising markets for flips, with strong appreciation rates and growing demand.

I wouldn’t consider Lima safe but it is a big city.

I live in a city where everyone knows that we have hard water.  

Recently, another tenant reported it to the City, and I received a code enforcement letter requiring a permit for the HVAC.

I'm assumming that there are CAP variations within the City.
