@Harshdeep Gupta I completed my first out-of-state BRRRR earlier this year. I purchased the property from a wholesaler, but I was working with a real estate agent who was then given the keys. Even though I had to pay the real estate agent a commission, it helps to have someone there that can coordinate these details. I ended flying out there shortly after close and put the new lockbox on, but that wasn't required.
I could have also had my property manager receive the keys, and I think I'll involve them on the next property so I don't necessarily have to make another trip. Even if you're going to BRRRR it helps to get a property manager involved right away. They can take care of mowing the lawn and shoveling snow in the winter. Mine was also able to meet contractors at the property if needed, although many were able to just use the lockbox. They can also provide input on what rehab you should perform in order to have the place ready to rent.
There's a small monthly fee (mine was $35/mo) for the property management administrative costs prior to renting. There is also a cost for them to visit the property and do the mowing/shoveling, but you would have to find and pay someone anyway. My place needed space heaters since the furnace was not working yet, so the property manager placed these in the house. Mine also handled the final make-ready work and the cleaning, so they can do more than just manage the property after it is rented. It's really good to have someone providing input on what rehab/improvements are needed to get the place rented for the most $$, that's what the property manager can do.
