Paying an attorney is still a bargain compared to a problem tenant. 

Tell them to look at local listings which are comparable in terms of rooms.

Compare an extra hundred bucks a month to having to do a $10-15k renovation now, between tenants, and in a year after the new tenant leaves. 

All of these factors will pay off disproportionately over time compared to what it took to get them and is worth the time.

We don’t know any PMCs to recommend in the area mentioned, but since selecting the wrong PMC is usually more harmful than selecting a bad tenant, you might want to read our series about “How to Screen a PMC Better than a Tenant”:https://www.biggerpockets.com/member-blogs/3094/91877-how-to-screen-a-pmc-better-than-a-tenant-part-1-services-and-processesWe recommend you get management contracts from several PMCs and compare the services they cover and, more importantly, what they each DO NOT cover.

On new constructions in a fairly new area, how does property get appraised up to contract if there are very little or few comparables around?

Hi Napat,Make sure you are comparing Apples to Apples.For instance is the Contractor going to use Owens Corning Synthetic Underlayment, or X mil plastic sheeting or tar paper, or nothing because he believes (for instance) hail damage is less with nothing under the shingles, and the Ownes Corning guy is going to use the Owens Corning Synthetic Underlayment (???)
