thanks for the guidance @Kaushik Sarkar Since it's development it will take longer to get to the exit. 3 years could be right depending on the market, if the project requires entitlements, how long it takes for permits, no major utility obstacles, etc.

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.

Depending on your income level, you may be able to take some losses on your return.

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

question depends entirely on the area you are investing in.

Zillow has an easy application for them to fill out. it come back with a credit score and background info. 

I do it manually (and keep in mind, it also depends on the state and location - VRBO does for some and not for others, Airbnb does for some and not for others) I know many folks happy with Avalara though. 

Or, depending on the property you could go non-QM with like a DSCR loan and close in an LLC or partnership.

Please be careful that they might still be the dog and depending on the breed, your insurance may be in jeopardy.

Depends on the area.
