THanks @Hanif Ahmad - I only have some subs; I do a lot of the work myseld or with my father in law (retired contractor), so I don't really have any 'full service' people

I understand that rental properties are NOT going to help me retire. nor is it my plan to retire from rental properties.

I love it I am saving money on the interest and making massive cuts into my 30 year loan after I have x number of properties I will be using this method to steadily pay them of for my retirement and security but like anything that matters it takes hard work 

The current owner is looking to retire, so your prediction is accurate. 

I have done this 4 times and was planning on a 5th in 2018.now in the old days if you replaced your home you sold with one of equal or greater value @Bob Okenwa  I think a lot of house hackers just move out and keep that property as a rental.. so this would not affect them.who this affects is folks like me who have run up 500k equity exceed the annual income limits and want to retire.. and down size.. its an anti califorina tax  LOL.So for people to think this tax plan is only helping the higher earners  I see it the exact opposite. 

@Aaron Hunt I hope you're 10x your efforts and win the rat race to retirement. 

After living in Marlborough, it's not as "scary" as people make it out to be, and our street demographics were about 50% retired blue-collar folks who were often original owners (40 yrs +), and most people moving into the neighbourhood were younger immigrant families, usually with kids, typically as renters.

I'm looking to house hack so assuming everything panned out, I would move into one of the "units" that we created and once the rehab is complete, rent out the other units (In total have a 2/1 + 2/1 +1/1).FundingCash savings set aside for Real Estate ($8,800) + What I could loan myself from my retirement account ($12,428) = Total personal investment of $21,228.My first thought was that I would have to use an FHA loan due to low down payment, and probably a standard 203(k) to help cover the rehab costs.

It will come in handy when I decide where I will retire at. 

I would like to begin with learn wholesaling, add flipping, and ultimately build a portfolio of properties to hold for retirement.
