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.Section 8: Rents are too high for the program and cash paying tenants are better overall.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 yearsSection 8: Rents are usually too high for the program.Class C Properties:Cashflow vs Appreciation: Typically, high cashflow and at the lower end of relative rent & value appreciation.

Now, you need to figure out how to find deals and pay for them.

Maybe it is ok if it is for you to live there and enjoy the amenities, but no need for you to pay high dues for a tenant to use the pool.Many condos don't qualify for FHA financing in Dallas. 

If I identified the offender, I would probably bill them back for the wasted water and when they didn't pay evict them, or non-renew them if their lease was near the end because that is simpler. 

Your son is likely paying more than the property is worth, by definition, as the seller would almost certainly prefer a similar offer that was not subject to. 

Value: I am paying current market value. 

I've never been to a pay laundry that didn't take twice as much drying as washing but not 10 times.   

It may sound nice to pay a 6% management fee but the extra fees can add up to be more than the other company that charges 10% with no additional fees.

I am not yet familiar with the management fees for an STR yet as we self manage, however Cleveland itself is currently STR friendly and just requires them to be registered if you have stays over 90 days and then you register with the city and pay $35.

On these very forums you hear countless stories of "I lost 5K and can't pay for me medical expenses".
