Ok I'm new to the field but u already invested Nd have two properties my biggest issues has been the contractors their quality of work has been a nightmare.

Of course, the quality of the works is most important because it will be my brand equity.

I am looking at using flipping and BRRRR methods for my own personal REI.

A contractor will be faster and probably better quality work.

Finding a contractor you trust and who does quality work is the biggest factor, but this is hard to do from afar and referrals may be your best bet.

My problem with the 3rd (and easiest for the landlord) method is that could end up being quite a few people who don't have a chance of qualifying that end up paying a non-refundable background check etc fee. 

Nope, for the most part you have to look through all the listings like everyone else, but many search methods will let you filter for short sales, and agents can filter for short sales, probate, REOs etc.

The real play is to find a high quality tenant for the store-front.

Finding a new tenant long term would make sense if the market supports a high quality tenant and you want to manage but you dont seem to want to.

@Avery Mshawn Since its less than 5 units, the property is valued by the comparable sale method so the most accurate way to get a value are, in order: 1.
