You're absolutely right—positive cash flow from rentals can vary significantly depending on factors like property costs, financing, and the ever changing market conditions.For real estate the challenge isn't just accumulating properties but creating a framework that builds net worth more strategically and sustainably.Cash Flow can be generated in many ways, my intention was to better understand the investor mindset and their approach, if they wanted to share.Based on your example, if using conservative calculations at $100K/door, you would pay $20M for access to $40K/month. 

I am using a dscr loan. what I cant understand, is why are my closing costs so high. above is the numbers on the refi.

Cost a lot $8000 for 12 months.

Another costly item for them to evict us.

I have not paid retail for RE in many years and would not in my high cost market (average SFH is ~$1m).  

Cost used is $25,000. 

While this can be good for long-term appreciation, it can also impact cash flow for buy-and-hold investors.Insurance Costs: Florida's hurricane risk can translate to higher insurance premiums for property owners.Competition: Florida's popularity attracts a lot of investors.

Quote from @John Davey: Id appreciate any help, as ex. if i take out say 100k home equity loan and use 50k each as down payments/cloing costs my understanding is i cant deduct the interest?

Larger properties offer economies of scale and better financing terms, but they also come with more complexities and higher upfront costs.

Prices are through the roof, Insurance cost have skyrocketed, maintenance cost are up a lot, taxes.
