My recommendation is that you self-evaluate and perform a mind shift. The answers are right in front of you.
1) A job is just a source of income, it is not "who we are". It is often easier to qualify for a new mortgage with one. I suspect that the "rat race" you feel is because there is a perception that this time spent in your job, is your primary income. If so, find ways to diversity. I have a job aside from being a Realtor (it is a side hustle for me). I commit 40 waking hours per week to my job (so what), that leaves 79 hours for side hustles and fun (I didn't count the 7 hours per night for sleeping). It provides subsidized health insurance, PTO, other benefits that my side hustles don't provide. I go look at homes or meet with clients on my lunch break. I look at this forum and others on my regular breaks. Your engineering background is a win. It will help you evaluate all the mousetraps together, to pick the best one for your needs. And let you realize there is no 100% perfect model.
2) Amount of doors is irrelevant, cash flow is paramount. I used to think $100 a door was a decent goal until I realized that 1 month of vacancy rips net profit out the door for the whole year. Now I shoot for a larger number.
3) I look at all investments, and ask the question, "In one year, will I kick myself for not pulling the trigger?" If yes, then pull the trigger. If I don't have the money to pull the trigger, go find or build it. Read "Profit First". I didn't become a Realtor for a job, I became one to get paid a transaction fee for helping myself, friends, and family; to build capital.
4) Real estate investing is just another way to invest and diversify that may provide cash flow or appreciation fueled by leverage. It should be taken in stride and compared against all other types. I find that diversification affords me less stress and I realize that there is no such thing as the 100% perfect model.
Want an easy way to measure? Project capital gains or cash flow into the future versus investment required. Yes, there is a little bit of speculation involved, but you can also evaluate base on past returns. The point is to make money grow, to beat inflation.
Every house I look at has potential, but they all don't make fiscal sense. If I can't see getting a 1.4+ DSCR on a house and/or the appreciation does not add to the net return, in my opinion, it is not worth investing in it. Likewise, I don't see the point in investing in stocks that only pay a 3% dividend, or that do not appreciate at least 10% annually.
I looked in your area, if the average price is $220,000, appreciation is 1% or less, and it costs 6% (not including any estate tax etc) to sell at the highest value to realize your capital gains, you are going to need to hold onto it 5-6 years before you can break even. What about cash flow? If it only cash flows $100 per month, for a return on $1,200, maybe you can but that break-even point to 4 years? And probably only if there is no vacancy. Is that better than investing in Moderna right now or an index fund that performs at 10%+? If the initial investment is $11,000 (5% of $220,000) what is the apples-to-apples comparison? If I buy Moderna at $110 per share and it goes up to $150 in a year, I will have made $4,000. My cost to sell is negligible @ $10, so not even worth bothering with it. If I hold it another year, and it goes up $40 again, now I am way up. Now let's say you can buy a house or multi-family that will cash flow that or better per year and cover the interest expense, even if there is little return on the appreciation, then purchasing the house is better.
My 2 cents.
