I am a highly motivated individual, however, and I'm dedicated to getting into real estate investing.  

Self-driving cars are potentially amazing, but they need to capture a lot of nuance and complexities.

@Micah Huffman unless you are going to commit to learning some basics about being a landlord AND are willing to commit at least 2-4 hours each month managing a Property Management Company - it's probably best you sell.Otherwise, it's highly likely you could lose more due to bad tenants and management.

However, the cost-effectiveness of such a mandate is highly questionable, and the resources required for compliance may be better spent elsewhere.

Keeping rehab costs in check means focusing on high-impact upgrades like kitchens, bathrooms, and curb appeal, while avoiding over-improving the property.

Refinance is one way to do it, if you want to avoid getting new debt because cash flow is high look into lease options to buy or executory contracts.

It’s worth considering self managing as a STR for depreciation benefits if the demand is there

Focus on high-demand rental areas (suburbs for multifamily, tourist/business hubs for STRs) and consider scaling with the BRRRR method to build passive income.
