I openly share the historical performance of my Detroit rentals for anyone interested.

FinancingADUs are rather difficult to finance historically, but that is getting somewhat easier.

This has become challenging due to an increased interest in the historic district in Dubuque due to revitalization plans that include 18 million dollar investment into the historic downtown area. 

The "high appreciation rates" you mention should be verified with recent data and be specific to the neighborhoods you're targeting.

I have some data that I would like to share with you.

: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.

Just another data point that RentRedi isn't ready for prime time.  

The sellers were only taking cash offers so we didn't look into SBA financing, but I think it would have been hard to do since there wasn't the right amount of historical cash flow.

I have a rare opportunity to purchase a beautiful old historic inn that I've had my eye on for about 15 years that just came on the market.

With all respect to AirDNA and the amazing data they provide for STR owners, their pricing tool is not on par with most tools available there.
