Hi @Temethy Najarro and welcome to BiggerPockets! I would recommend you examine your investment model and consider replacing it with a better one. It sounds like you're currently operating the standard rental model, in which your revenue comes entirely from rent. There are other models, like lease-purchase, owner financing, and vacation rental, that offer more sources of income (like non-refundable earnest money and down payment funds) or just more income for the same effort your expending now.
BP is the perfect place to learn about these other models. There are a ton of podcasts, blog entries, and forum posts on investment models you may not be familiar with.
