After some research, it seems, there is nothing illegal about it, as long as there is not active knocking/engaging with the home owner, as well as staying away from communities whos HOA has a no trespassing signI get them all the time at my house, but they are usually for restaurants, which isn't offensive at all, which is why people probably won't complain and much as "I would like to help you sell your house if your house, etc"If anyone has any advice or knowledge about possible fines associated with this it would be much appreciated. 

Hi BP members, what are your thoughts on 4-8 plex (1-2 Units) condos / apartments that are apart of a larger association (10 units)?

Try Belk & Associates.

Look for local landlord association meetings.All real estate is local.

Mostly because their buddies, family member or associates control the market.  

Read books from other successful investors, listen to podcasts, and join your local Real Estate Investing Association.

Any of those things that exists or are  may have major costs associated with your improvements. 

Go to the Milwaukee Real Estate Investor Association meeting on 8/14, in Brookfield. 

You can invest that cash as you please, including putting it back into real estate if you wish, without the time deadlines associated with 1031 exchanges.
