Cash flow is your margin of safety, it makes it so you won’t go under if the value of your property goes down.

(How is that a safety condition) All kinds of issues plus more that would arise AFTER lease signed AS THEY ALWAYS DO.

Ifa nonprofit wants to acquire a property which is subject to one or more of these types of liens, it shouldalways inquire if the governmental entity which holds the lien has any special programs or exemptionsfor nonprofits intending to develop the properties for charitable purposes which may enable the non-profit to obtain a release of the lien for less than the face value of the indebtedness secured by the lien.The City of Dallas, for example, has offered a program for nonprofit housing organizations wherebyhealth and safety liens are released if the property is used for affordable housing.General State Tax LiensEach county clerk maintains a State Tax Liens record or book in which notices of state taxliens filed by the Comptroller of Public Accounts are maintained.
