The reason not to upgrade, is that you won't get that much more income for the cost of the upgrades.  

Disclosure: Previous, current and future purchaser of Matt Scott's services.I have personally used Matt Scott and Incite Venture Capital to create my fixed income fund.

Everything I'm finding says 27.5 years due to it being rental income but others say 5 years because it's an RV.

At that time, my friend encouraged me to get into real estate with the idea of creating passive income and wealth in future (via appreciation).

It's going to offer Strong economic growth, Appreciation (especially in DFW), Tax advantages (no state income tax), and a Growing population, including infrastructure and amenities. 

Quote from @Alec Barnes: Quote from @Drew Sygit: @Alec Barnes we use Debt-To-Income Ratio (DTI) instead of income = 3x rent.Reason?

@Chris,Interesting points but I don't look for FHA or Fannie/Freddie loans as my income varies quite a bit and I deal mainly in commercial properties so I'm usually getting a commercial loan that originates from a bank or credit union.

The income of a property manager is dependent on whether you property is filled with tenants as well. 

FHA now allows us to count rental income from an ADU (additional dwelling unit) to help borrowers qualify.

They don't mention anything about paying payroll taxes, workers comp, complying with laws, etcReal estate agents can have a team around them where they do have employees if they have admin/support or marketing team.Regardless, if you want to interchange small business for commissioned sales people in my post you can.My post was mentioning that service providers in the real estate space are incentivized by their advertisements as it will increase their annual income.
