Specifically in NYC there is strategic value in having offices due to the advertising and financial industries. 

It is on a large peninsula, with one main road, so advertising with a few simple signs covers the entire area. 

The first attorney I picked thought I was acting as a realtor,  so make sure to advertise your contract, NOT the house

Just bought a duplex in Davenport....so will see how quick I fill it, have some minor maintenance to take care of then should be advertising in a week or two for it.

Maybe something that could be leased to someone, or even one that you could purchase a billboard to sell advertising for.

Licensing fees, mls, board, e&o insurance, general liability insurance, increased auto insurance, ce credits, electronic lockbox access etc.

Since syndicators cannot advertise investment opportunities for non-accredited investors, sophisticated investors who wish to invest should be active and network with syndicators to get access to deals.

I need advice on setting a rent price, property management ( If I should do it myself or 3rd party), advertising, property taxes, property insurance (Do I need to switch my insurance before I rent it out?)

The rest of the year is a mix of Airbnb and VRBO, we no longer advertise on CL as it just didn't yield much results.  

I always refer out my good vendors, and so far they have always been very grateful and I get the benefit of priority, small freebies, and overall better work.With referrals, you are still a source of income as a customer, but you are also a source of income as advertisement, making you more valuable to them.If you have enough work to keep them nearly full time employed then it may be a different scenario.
