My plans are to live in one unit, rent one unit as a furnished executive apt @ $2500/month and rent the 3rd unit through Airbnb @ $3500/month.

@Jason Nguyen STR’s have been very successful for many just like any other investing strategy but getting your plan down and executing properly is the most important.

Then you're having faith that in 3 or less years this tenant is going to repair their credit/financial situation enough to qualify for bank financing once the option is ready to execute.

They are responsible for finding the deals, doing the due diligence, setting up the financing, raising the capital, creating and executing the business plan, dealing with the operational challenges that come up 24 hours a day, managing the cash flow, and ultimately distributing the profits to all of the partners throughout the hold period.Good General Partners have been involved in the business for years, and they have perfected their business procedures to make sure the business plan is executed as effectively as possible.

Can I execute the lease with the dba, "Sunshine Properties", as the Lessor/Landlord in the lease agreement without it compromising the validity of the lease or causing any problems down the line? 

If it is only profitable by relying on more of your assets, then it isn't really profitable at all.Also, note the difference between the analysis and the execution in this case.  

Congrats on your vision and impressive execution!

Finding cash flow deals is getting increasingly more difficult with climbing rates.Depending on what your property would appraise for now, following your lipstick renovations and equity from landing a discounted buy, it might be worth looking into doing a BRRRR (Buy, Rehab, Rent, Refinance, Repeat).In executing a BRRRR, you'd do a cash-out refinance to recapitalize/remove the majority, if not all of your initial investment of $27,000.

Properly executed, an investment in these kinds of property can garner passive losses equal to or greater than the amount of capital invested. 

It sets the stage for a project that could alter investment and development across the Westside for a generation.Impact on Grove Park: “We are continuing to monitor the scale of this investment,” said Debra Edelson, executive director of the Grove Park Foundation.
