What are the four government powers that affect real property?

The four government powers that affect real property are police power, eminent domain, taxation, and escheat, remembered by the acronym PETE. Police power is the government's right to regulate property use for public health, safety, and welfare through zoning and building codes. Eminent domain is the right to take private property for public use with just compensation. Taxation is the right to levy charges on property to fund government services. Escheat is the government's right to take ownership of property when the owner dies without a will and without heirs.
