Personally, I really like the BRRR (Buy, Fix, Rent, Refinance Repeat) model, which is to buy a property fix it up, rent it out and refinance it and do another one. 

Instead of simply sharing content from other sources, model and repost while giving credit to the original creators.

Your situation (different country, Airbnb income, longer hold time) may not fit this model exactly.Negotiating Better Terms:With the bank: Shop around for better rates, consider a larger down payment for better terms.With real estate agents: Offer exclusivity for a lower rate, or consider handling the sale yourself if legal in Georgia.Holding Period: Given the strong Airbnb cash flow, holding longer could be beneficial, especially if the market is appreciating.

An old tv infomercial championed you to get rich quick and sit on the fan tail of a Luxury yacht sipping a tall cool drink surrounded by swimsuit clad models.

Am I thinking of converting this property for SRO/PadSplit model where refinancing may be harder to do because of property improvements I have made?

Carefully financially model this, so you make a profit.5.  

I have a building that I recently modeled.

Brokerages may need to adjust their business models, which could open up opportunities for cost-efficient, flat-fee models or other discount real estate services.

But obviously, we have spent the better part of 20 years on the buyer's side of the table, so we are looking for some general advice, tips/tricks, or even the pitfalls of setting up a hard money lending arm to augment our current business model. 

Although a different business model then you have been successful with I am really trying to dial in some of the expenses.
