17 Year Plan for retirement

[William McDaniel]

Hello, I am starting to consider getting into multi-family units with the very specific goal of replacing my current day job income when I plan to retire at 62.  Here are my current thoughts and situation and looking to get some advice.  I have zero real estate experience besides my own house and what I have researched using the bigger pockets websites.  I am fairly handy but do not want to be involved with big jobs. ie roof replacements etc.  

Goal: 

1. Replace $175K (Estimated salary at my current day job at 62) a year by purchasing up to ten 4 door multi-family units over the next several years.  

How I plan on doing it:  

1. Continue to work my current day job and purchase up to up to ten 4 door multi-family units over the next several years

2. Finance all units on a 15 year or less fixed rate mortgage.

3. Do not use any of the cashflow for personal income until all 10 units are paid off or 62 years old which ever comes first.

4. Use snowball effect to pay down mortgages as quickly as possible.

5. Once sustainable and I have a few units, centralize vacancy expenses, capital expenses and repairs to free up cashflow and pay down more.  

6. Invest personal cash from day job income into plan. Up to $3K a month

7. Stay focused on $250K - $400K priced units which are common in this area.

8. Do not lose focus of the main goal and try not to conquer the world (My personality)

My current financial situation:

1.  I am currently 44 years old, married, soon to be empty nesters and have no debt but my house. 

2. I could have access to up to $100k cash if I sold my truck and few toys to help start this process.

3. I plan on continuing to invest heavily in my 401K for diversity at age 62.

Questions:

1. Is this feasible?

2. What am I not seeing in this plan that could sabotage it?

3. Anyone else out there doing the same thing?  If so, how is it working out for you?

Thanks for your input!
