The biggest challenge we faced is the property's proximity to a railroad, which has proven to be an impediment to the sale.

We have no control of the condition of your property, if the value will appraise at where you feel it will appraise at, selecting specific appraisers, making sure the title to your property is free of any liens/judgements, what the title company will charge you, how much the AMC will charge you for an appraisal, what your property taxes will be, how much your insurance will cost you, and the list goes on.. 

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.

On the flip side, I am in the process of acquiring over $1.5M in defaulted DSCR loans form borrowers who are your age that put 25% down but had no money to fix any of the problems  = lost the renters and walked from the property.

As long as the ADU is under 900 sq. ft. and meets the state building code, there will be no variance or special permit needed, so no ZBA or neighborhood meetings.

Because people can be a bit fickle at times, I'm worried that I will schedule an Open House and no shows up even after confirming that they were coming. 

My initial reaction was "hell no".Algorithms are usually poor estimators of actual value.  

Tenants must receive; signed Certificate of Rental Suitability no more than 60 days before move-in, Partners in Good Housing Pamphlet, Lead Free/Safe Cert (if built before 1978), smoking policy for multi-unit properties, Bed Bug notice as you describe above.For Pennsylvania: It's also best practice for property owners to include a lease provision that waives the Notice to Quit requirement of the PA Landlord Tenant Act.

There’s no magic potion.

Amazing, no debt and 10k before graduating!
