But I just don’t know the rules and regulations and market demand on pre-decorated property for tenants and given that how to approach buying furniture for now.

As you research, pay attention to the short term rental regulations in the city/HOA where you are looking. 

Some states may have regulations on what you can/can not ask.

Hi, I am having a difficult time finding 5-50 unit small apartment owner occupied loans are there regulations against this or am I just not typing the correct terms to search for a lender that offers this ?

Always check your latest updates for RE housing regulations within your local area.   

Fortunately, we are renting out a property in an area that has reasonable laws and regulations for landlords.

The lease survives the sale of the property and regulates termination.

1st... talk to a local attorney in your area and see if there are any regulations that are unique to your state, county, and/or city (or even subdivision in some places). 2nd... if the numbers work and you are up for managing six different tenants for a single property then go for it.

For example, right now in the name of regulations designed to protect investors (like 506b), sponsors are not allowed to share their performance information publicly.

Also, how do I safely talk to someone who knows both about real estate AND about tax, license, regulations?
