I took precautions so this wouldn't happen again but the damage had already been done.

The further away the better it seems.I've taken some precautions lately like asking for a phone call prior to making any repair more that $100.

I go after everything I want in life and I achieve all my goals but I take precaution because I'm not only supporting myself so I have to evaluate my risks carefully.

im an investor in ma...i currently have 14 units (on Monday it will be 17) lynn ma, a low income city north of boston...you are right there are great cash flowing properties out there right now in low income areas...there is also a ton of competition for those properties...i would not be afraid of investing just bc we live in a liberal state, dont let that stop you from being successful in this real estate market, it just might be the best chance of our lives...just take extra precautions to make sure your units are well kept, well lit, clean and safe, make sure you respond to the little things when tenants call w/ complaints...i have had a few evictions and they took a few months, most of the time these tenants never show for court...i try and show my face around my units at least a few times a week, and drive by almost daily...just dont be a slumlord and have pride in your properties even if your tenants dont...good luck

It seems to me that some investors may not be aware of why it is generally unwise for a business to also own the real estate used in the business.

Regardless of the fact you got a great deal on the real estate there ...

Instead, why not use that knowledge to take precautions such as swimming on patrolled beaches and enjoy the experience to the full?

Probably a VERY unlikely scenario to have "killed one" without killing the other but just a precaution.

Any precautions that I should be on the look out for when dealing with wholesalers?

As a precaution I would get a title insurance policy in case anything negative comes up, that policy will pay to clear that up completely. 

Then you will know more than you knew before and will be able to take precautions, such as encapsulation or removal of items with lead-based paint.Take RPP (renovation, repair, painting) training.
