Due to the current high interest rates and prices, many investors are choosing to increase their down payment to ensure a positive cash flow even in the not so "nice" areas and plan to refinance in the future.

The data reached an all-time high of 108.500 % in Mar 2012 and a record low of 94.900 % in Dec 2021.

You can refinance out of a high rate. 

Its not even in the news cycle about "ambulance chasing laywers" suing high networth individuals. 

The accuracy of the appraisal depends on the quantity and quality of market data available.

: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+, 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, 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.

I have not come across a rate that high.

@Jaron Walling My guess is you are probably spoiled having gotten into the RE market before this high tide? 

I expect high 3800-4100. 

If you can't keep control of your personal finances, you are highly unlikely to succeed in real estate investing.
