With some proper planning and the funds to lock in materials early, you can have an efficient build, but certainly not fast.

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.

However, with proper cash flowing properties, that would be well worth it in my opinion. 

I disagree with your sentiment about a bull market correlating to my genius I just manage risk properly with a model I have ran for years and in the past month / month and a half have made almost another 100,000.

I have done quite a few brrrr, but the market interest rate results in large negative cash flow when properly allocating expenses for a sustained hold.  

@Chris Kay to learn to properly DIY manage you have two basic options:1) Trial & fire on your own, hopefully not making a major mistake that costs you tens of thousands of dollars.- Once your time is more impotant to you then the cost of a PMC, you can hire one.2) Hire a PMC to guide you on your first rental and learn from their expertise.- You can buy additional properties and DIY manage those, perhaps leaning on the PMC for any issues you're not sure how to handle on your own.Good luck:)

The hard and the fun part is training my team there in the proper processes from planting all the way through selling.

The specialist I recommend you have is an attorney to properly draft the documents and a title company to facilitate the deal.

So, proper screening is EXTREMELY important!
