Your options in that price range with 5 bedrooms will be very limited so you may consider extending your search beyond Lake Worth is that is feasible. As of this morning there is one 5 bedroom home listed under $1,800 in Lake Work and it is located at 815 S D Street. Listed at $1,350 it shows 5 bedrooms in a total of 1,760 square feet so should be an interesting layout. After that prices jump up above $2,000.
If you would like to expand the search area or speak about your needs in more detail please feel free to contact me at your convenience.
The very best of luck to you and I hope this information is helpful but if you need anything additional please do not hesitate to give me a call.
Always at Your Service,
