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 of these folks don't want to lose their voucher.Additional issue, when rent is too high, it slows down leasing. 

I'm in New York but the prices (at least downstate) are much too high for me to make my first deal so looking more upstate and out of state. 

If prices are too high people will just go elsewhere.

For example, most Developers in the Seattle area are taking many properties and turning them to condos since that is a booming market with high rental rates And sometimes more conveniently built and accommodating then a SFH.

The rates are high right now but these loans are limited based on cashflow so you cant take a loan that costs more than you're receiving in rental income.

I use standard market PM rates in my underwriting, but I also would not work for those rates but it is fair compensation for the work.I typically use vacancy of 5% not because I have ever had a unit that had that high vacancy but I do not have a no payment category and I want the underwriting to be conservativeon the opposite, your rate is a bit high and your appreciation rate and rent growth are modest.overall, seems like a decent attempt at an analysis.  

If you are new to the business the most common issue is you're either locking up deals too high or you aren't finding attractive deals.

High risk areas.  3.

we are pretty high that is for sure.
