Can anyone share a little more information on transferring the ownership of property in your name to an LLC or any other entity for that matter?

Should we buy it under our LLC or under our name and then transfer it to our LLC after refinance?

BUY every time you transfer.

I was wondering, can I make a PLLC now and transfer that money to the PLLC retroactively?

But yes when you transfer the deed of the property into the LLC you will need to change your insurance policy accordingly. 

They also maintain an objective opinion and aren't caught up in the emotions or anxiety of a purchase.An Agent can work with you as a client (confidentiality, protecting your interests) while working with the seller as a customer (no confidentiality) and collecting a lower commission.Another option is to have an attorney fill out the contract, but they won't do well for market analysis, negotiation, etc.You can also get the contract from a Title Company and do it on your own.

If your return is pretty basic (i.e. no real estate), I'd recommend DIY and then once you buy the property you can easily transfer to a CPA in the first year of your real estate.
