This includes but business and personal filing and I’m curious if this is high, low, or right in line with what others are seeing.

Question is, if I have the means to put a high enough down payment on a house to be cash flow positive (assuming my expense estimates are accurate, etc.) is that something that I should do?  

I have been trying to educate myself through videos, books, and podcasts.

I do not have my numbers as well organized as @Greg Scott but my estimate is upper 20% annual return on average.The 3 i am currently invested in, one seems likely to produce an outstanding return (High risk, high reward), one is conservative and is performing to projections, and one i have significant concerns about but has not had a capital call.  

It's a scary high %. 

It's not profit until you access it in some form of cash.I've seen investors loss properties with equity (a few with a lot of equity) because they can't sell at a price high enough to gain that equity, or because they can't refinance it due to the negative CF,...which would increase with a new mortgage.

BiggerPockets also has a calculator to analyze deals, and I highly recommend you start this as soon as possible, even if you are not ready to buy.

Most serious and qualified tenants are searching on the major 3rd party platforms you mentioned + realtor.com, redfin, and a few others.Apartments.com & homes.com are owned by the same company and may offer some additional marketing options.Another strategy to consider here is social media - video marketing.

Interest rates are high relative to house prices, this won’t last forever.  

Instead of tying up your capital in a high-cost primary residence, consider taking the would-be down payment and investing it in out-of-state properties.This strategy allows you to diversify your portfolio across multiple assets, spreading risk while potentially generating cash flow and building equity in appreciating markets.
