For rentals in an LLC, most lenders look at the cash flow of the property (aka DSC Ratio: Debt Service  Coverage) and your credit score rather than your personal income.

We had a wash & fold service with pickup & delivery, which added complexity to the operation.

If you are going to outsource management you will get everything done for you, but you will have some of your cash flow used for services. 

You are not paying for their services and won't cost you anything extra anyways. 

@Alecia Loveless is correct--tenants need access 24/7 to their electric service panel, water and heat, assuming those are individual utilities for each unit. 

Many of my customers who are traveling nurses buy condos or townhomes in Florida as vacation homes, then rent them out when they're not in town.This system has proven to be very lucrative, as it allows them to service the mortgage debt and generate a good cash flow.

I can't continue providing that service if the landlord takes over management.

I work for Evernest, a full-service PM company, here in Birmingham. 

I suggest using a service like Mayistay.

They can also give you a better idea of how much you should be prepared to pay so you can cruise through your closing with confidence.And as you plan ahead for closing day, be sure to budget for your real estate agent’s professional service fee too, in case the seller doesn’t cover it.
