You can often get better rates with a national lender, but the customer service is non-existent, communication probably sucks, they may ask for the same documents multiple times, etc.

I ran a new electrical service up to the apartment and replaced all plumbing.  

Based on my research, this PM company is highly reputable and provides excellent service.

LLC-A deducts the 10% management fee, while LLC-B reports it as active income, subject to self-employment tax but eligible for tax-efficient salary and distribution strategies.Ensure the setup has a clear business purpose, reasonable compensation, and documented management services to avoid IRS scrutiny.

I’d love to hear about your goals and what you’re hoping to achieve here.

You'll probably get better service approaching it that way than hiring a professional manager anyway.  

I would include servicing costs of the loan and licensing costs.

and I was just one little mortgage guy with 450 loans out.. can you imagine the banks with hundreds of thousands of loans and servicing companies.. so having mass equity or paid for keeps this from ever being an issue. then when I sold these off.. most for cash but a lot I did a 30 to 60 month ZERO interest deal on.... and boy you should have heard the cash flow cool laid drinkers..

I have read I will need to use a third party service to make this happen.  

That is probably a good start to setting the goals you need to achieve to make the dream happen.
