In 2015, my sister had a business which was essentially her livelihood.

More than anything, real estate is a people business.

Also If the names are correct i searched dca database and found neither license listed under the name or business. 

The platform aims to provide investors with everything they need to run and scale a successful real estate investment business in one place.

A good real estate accountant can save you thousands of dollars by leveraging entity selection and formation, tax deductions, cost segregations, bonus depreciation and tax planning.I recommend finding an accountant specializing in real estate taxation, business taxation, financial planning and tax planning.Consider working with your accountant remotely to expand your options.I would also recommend looking for an accountant willing to work with you throughout the year.

You're running a business...the tenant does not 'inform' you when they will be paying their rent...they are contractually liable for paying at specific amount on a specific day. 

Only reason I've been doing it is to get 0% business credit card limit increases.  

I found a really nice brick building with 12 apartments, 3 commercial business units and some garages.

I was able to rent the garage to a seasoned electrician running his business through there only coming in and out to stock his truck once per day.I hope to be able to convert the second floor into an ADU as soon as Feb 2nd rolls around.

You can't use a PO Box for a business entity.
