@Ned Carey who, along with his investment partner, has the corner lock on tax lien investing in Baltimore (in terms of know-how and experience) and Anthony Onwuanibe who is a tax lien attorney.http://www.meetup.com/bwimeetupThis meeting is FREE - you will learn a ton.  

I also don't love the idea of being completely vulnerable to rising interest rates (most if not all commercial loans seem to reset every 5 years.)yes most of them are through community banks portfolio lenders, 5 yr lock. 5 to 7% interest. 

We recently found out that the cousin even changed the locks of the house and hasn't given us a copy of the key when we asked for one.

I'd like to take advantage of low interest rates and get locked into as many good properties as possible soon.

So I purchased a 5 acre piece of land that appears to be land locked but has a 25 ft access easement across the adjacent property.  

If you have a low rate locked in, why not keep it?

You need to lock down what the net operating income (NOI) is by subtracting the taxes and CAM from the total rental income.

My bigger question is, assuming my offer is accepted and I begin my due diligence part of the home inspection, am I locked into the home without anyway out since I signed the "meth discloser" along with my offer?

This locks in my profit for my IP and effort, assures them of a return on their capital and allows us to share in the profits on an equitable basis.

Has the property increase in value since you locked in the purchase price?
