Next generation is on the way!!!!

My family is welcoming the next generation and we need more room. The problem is we can only afford $500-$600 max. Therefore we are in need of help.
Looking for a 3 or more bedroom house for sale that is one or more of these, in or near the Caballo, NM area, as me and my husband are members of the Caballo Volunteer Fire Department and we want to be closer. We have 3 boys and our daughter, who has 1 on the way.

We are currently living in a 3 bedroom trailer that has had a window missing since last summer..There are a lot of 3 bedroom rentals in the area but we just can not afford the rent, I hoping to get enough for a down payment on a place that we can expand if we need to. Most of the properties in the area are manufactured homes, (trailers), we need a bit more space for that. I am really hoping to get the help that we sorely need.

Thank you in advance for reading this and passing it on.
