Once you feel you know what they might want, you can always quickly swing by these properties to check them out, thus eliminating the nuisance of coordinating, trekking around, etc. 

They often have a vested interest in surrounding properties as noise, clutter or whatever is a nuisance. 

A thorough response as always.I have my own take, and as any attorney will say, this is not legal advice...For the asset protection purposes you need both (1) insurance and (2) properly structured company for litigation protection, an LLC/LP/etc.Insurance protects your from nuisance that occur on the property; i.e. slip and fallThe company structure protects your assets from litigation liability; i.e. gross negligence (health and safety, alleged known hazards, fraud in the sale of the property) as well as someone getting to your assets by suing you personally (e.x. you got into a car wreck that exceeded the coverage of your policy, now they can go after your assets)The due on sale clause is often a concern, but me and my colleagues view it as a very low risk for a number of reasons.

The majority of tenants will not leave for a nuisance 30-50 rent bump to market.  

If this property is hot on their radar as a nuisance, stay away.

Then I start listening and reading and learning and all these possibilities that I had never considered before, such as looking in my own back yard, financing options, etc.I also run (well, inherited and I'm keeping it on life support) a blog about vacant nuisance properties in DC.

The point was that with the HOA, I have a risk of losing my house and currently my HOA doesn't seem to add any value by enforcing the nuisance rules, though I've heard horror stories about old ladies losing their paid off homes because of the wrong type of flowers being planted, etc.The HOA doesn't seem to add much value because they don't currently enforce rules but at any year that could change if enough people complain and it could swing the other way.

If you are in the cashier's-check-only camp, do you find it a nuisance trying to lock up a deal on the weekend when it is extremely difficult for a buyer to get a cashier's check since banks are closed?

Maybe you could sue the other property owner for creating a nuisance.

I begin investing in Tax Liens approximately two weeks ago.I felt the timing was right and since I had some disposable income, I jump head first.I am still relatively new to the area and invited a fellow business colleague to assist me with accessing some of the areas; well a partnership was born.Although, we are both novices in Tax Liens, I have a solid background in researching topics (mostly taxation) but I digress so I felt mildly comfortable with this sudden turn of events.Well in hindsight, my partner and I management style is vastly different; this is where the slight nuisances started to appear.
