I've only been practicing direct mail for the past few months.

Is this a practice that is sanctioned by Airbnb?

Disclaimer: While I’m an attorney licensed to practice in PA, I’m not your attorney.

I can potentially offer value by practicing this skill on deals of your own or by assisting with other areas of your business.For now, I would like to limit my target areas to the Livonia/Westland area.

In my years of practice, I have only had one client request for my CPA license number. 

And that takes tactfulness (which I'm still working on) when communicating with your partner and mutual respect.Lastly, I'll leave you with one practical thing that works really well for me and my wife (In business and everyday life).

I have been reading everything I can, listening to every podcast, I joined my local REIA association and trying to learn as much as I can.I have an strong practice as an Architect, (not licensed in the USA just in case) design, and construction. 

I'm doing my due dilligence while I roughly scout for properties on zillow/trulia for practice analysis and learning about the specific market demographics.

As for taxes, there is no practical difference in tax burden whether you own this personally or in an LLC taxed as a partnership (other than the added LLC taxes from the state) because it is a pass-through entity and the taxes follow on to your personal return.

From a tax-deferral standpoint, it doesn't matter if you buy one property or 100 (note there are identification rules which will impose constraints on what is practical).
