Tucson has it's own and the last I knew the state of AZ has about 13 separate MLS's.The US recently had over 900 MLS's, the number is decreasing as consolidation takes place but it's a painfully slow and political process. 

We also did consolidation loans to lower our rates and free up loan slots (you are only allowed 10 Fannie Mae loans per person in the US).  

You can also roll over traditional IRAs and old traditional 401ks into it to consolidate.

@Josie Sweeney-Rogers Don't want to hijack your thread but was not sure if i need to post a new one or if it would be good to have consolidated info here.

I was thinking of consolidating properties into a commercial insurance policy, one that hopefully would insure all of them under one roof (one single policy I hope).

When I applied to consolidate my first and second mortgages with a new mortgage through a new lender, I applied alone but they wanted my husband on the loan/title of the property.

I'd like to make some renovations with the hopes to raise the value as well as absorb and consolidate some of the debt that I carry currently and have a surplus from the future second loan for the second closing cost.

@Joseph Udofia My Client would very much like to have a conversation with you regarding a Reverse Consolidation 1031 Exchange.

Never pay a collection agency and never consolidate collections. 

While foreclosures can often be found on public sites, if you are busy and want to save a bunch of time analyzing more property the lists typically are pretty cheap, like $30-$40 a month and can consolidate a bunch of information into easily digestable and sortable information.
