Heres a general breakdown:1960s: ~5 -“7%1970s: ~7 - 11% (rising due to inflation)1980s: ~10 - 18% (peaking at 18-19% in 1981-1982 due to high inflation)1990s: ~7 - 10% (gradual decline)2000s: ~5 - 7% (lower due to economic stability)2010s: ~3 - 5% (record lows after the 2008 financial crisis)2020s: ~2.7 - 7.8% (historically low in 2021, then rising in 2022-2023 due to Fed rate hikes)Long-Term AverageOver the past 50 - 60 years, the average mortgage rate has been around 7 - 8%In short and IMO, due to fiat system.

Keep in mind, it would be in your best interest to go for as high as 4 units on each purchase to maximize your door count. 

Quote from @Ben Trageser: Highly recommend Maven Cost Seg!

Not to mention sky-high drama factor.

Short-term rentals (STRs) are highly regulated, particularly downtown, so areas like Mount Pleasant, James Island, and North Charleston may offer more flexibility.

Coffered ceilings, low corner additions etc.Anyone can slap lipstick on a pig, looking for high value add in high demand markets is where the $ is.

I have 3 per property and find that to be the best way for me to take advantage of their high APY and also keep things super organized.

that we’ve learned in our 24 years, managing almost 700 doors across the Metro Detroit area, including almost 100 S8 leases:Class A Properties:Cashflow vs Appreciation: Typically, 3-5 years for positive cashflow, but you get highest relative rent & value appreciation.Vacancy Est: Historically 10%, 5% the more recent norm.Tenant Pool: Majority will have FICO scores of 680+ (roughly 5% probability of default), zero evictions in last 7 years.Class B Properties:Cashflow vs Appreciation: Typically, decent amount of relative rent & value appreciation.Vacancy Est: Historically 10%, 5% should be applied only if proper research done to support.Tenant Pool: Majority will have FICO scores of 620-680 (around 10% probability of default), some blemishes, but should have no evictions in last 5 yearsClass C Properties:Cashflow vs Appreciation: Typically, high cashflow and at the lower end of relative rent & value appreciation.

High rental demand (Section 8 too).

However I have used some of apifys scrapers (for non real estate uses) and was highly satisfied with the value for the price: https://apify.com/tri_angle/redfin-search It looks like it’s for listed properties only?
