The other option, how I found BRRRR and learned some basics of it, was the Bigger Pockets book.

But I would remain open to long-term rental as an option as this seems like a more stable option in terms of income, again this may be my inexperience talking.However, I have always  been somewhat risk averse and investing in real estate is always a big venture, in my opinion/experience, in terms of capital.

They won't always be upfront about this with you but if know they're selling because they want to retire, that opens you up to different options vs if they're an investor just selling for profit.

They don't allow auto payments or automatically add late fees, and tenants would have the option to pull their payment back, which is not ideal.

Focus on understanding the rental market, conducting thorough property inspections, and leveraging owner-occupied financing options like FHA loans.

Quote from @Brandon Croucier: Financing a commercial MF that runs as an STR is possible.Appraising a property based on the income is not, whos to say a buyer would STR the property. 

I also completely understand the frustration of navigating through "Joker brokers" and fake lenders who promise more than they can deliver—one of the biggest challenges in the industry today.Regarding your approach to accrual-based repayment options, that’s a huge help for flippers managing tight cash flow, and it's great that you offer that flexibility.

Since you know what you need to buy it at and an average rehab cost, I would say $50-70k for a cosmetic flip, set the ARV based on the sample you choose and doing comps and ask them if they would invest in a deal similar to this. 

Louis, Missouri, and based on the numbers, it seems like it could be a great fit for Section 8 tenants.I’d love to hear from anyone with experience in the St.

I think build to rent is a great option if you can get cheap enough land to make it worth it.
