did small renovations myself, added back decks, paint, new kitched appliances, etc.

Are you paying money to run ads just to help?

I tend to agree, I hate to lose all of my passive income just to eliminate my primary mortgage. just out of curiosity, what makes you say that an HOA is a hindrance?

The property also has a ~800 sqft basement, 400 sqft of which is finished and I plan to finish the rest by adding a full bathroom, and making two bedrooms (both will be egress but one will be more of a family room than bedroom). 

If your $150,000 properties appreciate by just 3%, they could be worth around $200,000 each in 10 years, adding significant equity.Additionally, mortgage paydown from tenants further builds equity.

This is without adding in an outside approval process.

I'm particularly interested in purchasing two-bedroom, one-bath (minimum) properties that offer space and potential for adding an extra bedroom and bathroom.

I saw an ad on IG the other day for a private lender who was going up to 96% of the purchase price and funding 100% of the renovation cost.

Also, the costs in Florida are high, with expenses for insurance and the hurricane risk adding up.

@Ronald RohdeYep, I would be adding the same thickness of slab and only extending the portion of the warehouse only, not any office etc.
