Managing vacation rentals remotely sounds like a unique challenge..

I suspect that you'll have better luck with a local bank or private money, though it likely will still be challenging. 

Any tools, APIs, or approaches you’d recommend?

Taking time for self-care and nurturing our well-being will empower us to tackle challenges with renewed energy and focus.As we move forward, let's celebrate each milestone, no matter how small, and remain resilient in the face of setbacks.

well I do plan on purchasing a duplex as my first investment and once I complete my Real Estate License during the time of my service I hope to be a lot more knowledgeable and approach SFH's to BRRRR but yes I understand!

Many lenders allow for low-down-payment options if the rental income covers the loan.You’re approaching this deal thoughtfully, but be sure to communicate the benefits of your offers clearly to overcome resistance from the seller's representative.

That is the biggest challenge I have with my clients.

That said, its a great opportunity for the investor willing to accept the challenge.  

Totally agree with your approach!

This approach helps manage costs while providing predictability for tenants.Thanks @Julia Lyrberg!
