The mailers I receive for my properties are not of a high enough quality, to make me believe the sender understands what gets a recipient to even open or read the mailer, let alone respond. 

Contractors, unless you have a working relationship with them, normally do not want you bouncing ideas off them.Understand what their hourly rate is, have a discussion with them that you are okay with paying them an hourly rate if they walk the property with you and provide you a scope of work along with an explanation of what you can/can't get away with in regards to improvements.ask them if you go with them, if they can credit you the amount that you paid.Once you develop a working relationship with a few contractors, you can bounce ideas off them and expect quality responses.I do not invest in New York.Best of luck. 

The license doesn't cost more, the service and quality does.And a note on that cost, in my experience hiring contractors, only a small percentage of the cost savings was due to finding the right guy who is willing to work for less.

They can't assess all the subjective data like overall layout, view from the living room window, the dogs next door that bark all day, the width of doorways, size of individual rooms, quality of kitchen cabinets and appliances, etc.The best thing to do is study your market regularly.

@Christopher HeidrichRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

A few small touches, like high-quality linens and a welcome guide, can make a big difference. 

Class A properties are going to cost you more, have lower cash flow, yet be more attractive to a higher quality tenant base.

Do everything right: To include but not limited to pro photos, professional quality design, durable furnishings.

Cost per lead (CPL) is crucial—it shows how much you're paying to get a potential seller or buyer’s info, and you want this as low as possible without sacrificing quality.
