My question to you all is how do you go about building a team and in what order do you recommend doing things?

I have a legal business in the U.S. that has been open 1.5 years and I'm wondering if anyone has any good recommendations for a personal or business loan that will give me the best rate for this purchase? 

Any recommendation for a good preferably open source rental management software that primarily handles back end accounting? 

However, upon transferring it back to your dad, the basis is not relevant anymore.In the end I would highly recommend you reach out to a tax professional here to get this sorted out.

I have a large paper trail with multiple inspections by their inspectors and appraisals by liscenced appraisers ordered by me and the bank as well as contractor receipts showing that I’m only half way through the list of recommended repairs from their inspector.

@Alexander Merritt My recommendation - repeating others - is buying the worst properties in the best neighborhoods.   

Also are there any recommendations for brokers as she is starting out? 

Every system you try will have flaws, or you may salivate over a feature that appears in other software.Some familiar names are mentioned frequently: Stessa, Apartments.com, RentRedi, TenantCloud, Innago, RentManager, Avail, Rentec Direct, Doorloop, etc.I recommend conducting thorough research on each app online to understand their offerings, pricing, etc.

First, you should recognize that investing with friends or family can be risky, which is why most people recommend you avoid it.

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?
