I think I’m more interested in BRRR rather than STR mostly based on the inventory.  

As you get up and running, having a diverse range of contacts— from wholesalers to hard money lenders — means more opportunities. 

This could lead to significant tax savings, especially if you're actively involved in the management and operations of your properties.Additionally, starting a property management company would allow you to deduct a wide range of business expenses related to managing your properties, such as office supplies, travel, marketing, and payroll (if you hire help).

And subsequently I bought and sold over 1,000 properties for my own inventory, and the last 100+ properties  were bought 100% cash.

All of my customers in NJ, NY, CT, CA, WA and other states are all buying in those states as well as a few others.The price to cash flow ratio is going to be better in those states as well as having a higher inventory of both single family and multifamily rental homes.

Also show market analysis of both inventory and rent rates compared to your plan. 

@Gabriel Dent Depending on your work and savings, it could be worth doing an application with a lender to see what you could get preapproved up to so you know what range you can offer within and then compare those duplexes, triplexes, and fourplexes to where you could rent for the time being instead. 

When ROE falls below this range, it might be a sign that your property has accumulated too much equity, and you could consider options like cash-out refinancing, selling, or 1031 exchanges to redeploy that equity into higher-yielding investments.During the growth phase, focus on maximizing returns by keeping your ROE within or above this range.

Here's the latest market report (based on single family homes): Mortgage Rates:30-year conventional rate today is 6.61%30-year VA rate today is 6.14% Median Sales Price:July: $487,483August: $480,000Sept: $490,000 New Listings:July: 2,068August: 2,198Sept: 1,910 Median Days on Market Until Sale:July: 14August: 16Sept: 20 Months Supply of Inventory:July: 2.8August: 3.1Sept: 3.1 What does "Months Supply of Inventory" mean?

@Robert MorrisI have seen this technique done by an older landlord/mom and pop owners of C class properties but it worked well for them because they were in a 20-50 unit range of properties that they were self managing - they were also local to their properties.
