The sales comparison approach is typically done for residential real estate and will be less appropriate and come in under value because there are no good comps, and even an appraisal using the income approach (unless the appraiser is trained to do more complex commercial appraisals) is probably not going to be the most accurate either because they typically use market cap rates and in this case you don’t have good comparable income properties to find the market cap for the analysis.  

I turned to the Diontalk Binder strategy which educates the tenants on the current price of market rents, section 8, etc, and what I could potentially earn if they were to move out ( In this case being 1500 for a 3b 1ba). they then realize this and know paying a $400 increase (36.6% Increase) would be the best option vs moving out, living in cheaper housing, or going to market rent in the area.

Lol Have you done many lease options as a buyer over many year term? 

In this case S8 is probably not a good option.If you are convinced you can find a great family that will take care of your property, then either option is fine for you. 

You won’t find many seller-financing deals here, so if you're looking to scale quickly, your next best option is the BRRRR method—using cash or hard money to acquire properties and DSCR loans to refinance into. 

Typically you aren't buying a fixer upper with a conventional loan.

I am grateful that you shared this, because I do think a lot of these gurus, while generally having good intentions, are typically very naive and lack experience to truly teach anything.  

Typically these repairs are mostly cosmetics.

Best to talk to her and understand your options.

We also had the option of another type of policy that was even less expensive that would have required us to spend at least 1 night in the house and rent it at least 30 nights each year.
