Coupled with persistently high interest rates that may last for years, rising insurance premiums are inevitable, regardless of your property’s condition.

I HIGHLY recommend you have a conversation with an attorney. 

If this $30k was instead invested in a taxable brokerage account, you'd pay capital gains taxes on the $70k of growth and be left with a tax bill as high as $14k.

The hold time is usually between three and five years, and the overall gain is pretty high within a fairly short time frame.

Seems high.

From my experience, you can use that savings to house hack with an FHA loan, invest in a turnkey property in a more affordable market, or even partner with others to expand your purchasing power.

Have you explored any potential house hack opportunities in NY, or is the price threshold too high to tackle, and thus, you are considering Columbus? 

That gets worse as you get farther out of the cityTLDR: values depreciate, inflation has gone basically nowhere in Japan for a long time, the supply of housing is pretty good compared to demand (unlike the US) and that's because of flexibility with rezoning and development, taxes on rental income are high. 

that we’ve learned in our 24 years, managing almost 700 doors across the Metro Detroit area, including almost 100 S8 leases:Class A Properties:Cashflow vs Appreciation: Typically, 3-5 years for positive cashflow, but you get highest relative rent & value appreciation.Vacancy Est: Historically 10%, 5% the more recent norm.Tenant Pool: Majority will have FICO scores of 680+ (roughly 5% probability of default), zero evictions in last 7 years.Class B Properties:Cashflow vs Appreciation: Typically, decent amount of relative rent & value appreciation.Vacancy Est: Historically 10%, 5% should be applied only if proper research done to support.Tenant Pool: Majority will have FICO scores of 620-680 (around 10% probability of default), some blemishes, but should have no evictions in last 5 yearsClass C Properties:Cashflow vs Appreciation: Typically, high cashflow and at the lower end of relative rent & value appreciation.

Most CFO clients that I work with that are new construction/home builders usually target a 20%-25% gross margin as they usually have to deliver high teen returns to their investors.Great question.
