Two things are certain, 1) taxes are lower today than they've ever been in the past 80 years. 2) they are certain to be higher in the future.We should all be focused on paying the lowest “lifetime tax bill” not the “lowest tax bill this year”.By paying 20% and settling up my long-term capital gains is not a bad deal.

Balancing that with wanting to do something to maintain affordable housing for those in mid to lower income brackets.  

Go for a lower downpayment. 

Payments stay lower, cashflow better and it'll boost your balance sheet not to mention lower risk when things go awry. 

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.

Try looking for lower priced mobile homes on private property that need to be moved. 

Then they lock them in to a SLIGHTLY lower initial cost per kWh.

Make the place nicer or lower the price to get bargain shoppers. 

I would definitely factor in some substantial capex/ maintenance and repair costs which could lower your returns.  

Most who try to replace their W2 income invest in less sustainable investment methods: investing in lower tier neighborhoods that cash flow well in spreadsheets or flipping homes.
