I have an opportunity to Purchase a Turn Key Business.

The property already had a cash-flowing business located on the property with no real-estate options.

I recommend that you work with an accountant who specializes in real estate taxation. 

Quote from @Manuel Perez Corrales: Hello,I would appreciate it a lot if someone could put me in contact or refer a lawyer that could help establish a partnership between me (resident of the Netherlands and not a US citizen), and my sister and my brother in law (both US citizens and living in the US) to buy real estate property specifically in Maryland and/or North Virginia. 

Research key rental markets like Spring Branch, Katy, and Pasadena, and connect with VA-friendly lenders and local investor groups to build your network.

However, if the intent changes and you convert it to a rental, you can start deducting rental losses, depreciation, mortgage interest, and expenses from that point forward.Rental losses are generally passive and can only offset passive income unless you qualify as a Real Estate Professional (REPS) or meet the $25K active investor deduction (phases out at $100K-$150K AGI).To document intent, keep records showing marketing efforts to sell vs. rental agreements to support tax treatment.

You personally guarantee business credit just as you do real estate loans so there is no true separation.

I am getting into Real-estate Wholesaling. 

Also, BiggerPockets is a goldmine for learning and networking.2.Networking is Key – Join local real estate meetups, attend auctions, and connect with investors, wholesalers, and contractors in your area.3.Choose a Starting Strategy – House flipping and rentals are both great options, but consider starting with one.

For general real estate knowledge, I took the 'real estate broker class' that was a few hundred dollars.
