lost with accomodation!

[djamila1981]

hello,
question regarding the accomodation for the spouse visa.
i am british married to an algerian man, we have 3 kids (10-5-3) and we all live in algeria.
we apply through savings.

my husand is the applicant. we have no accomodation in the uk. we all want to move back together.
we are lost with the accomodation issue.
we have family but none with a house big enough for 5 more people.

so now we are stuck with the accomodation requirements.
these are our options:

1- ask for a relative to write a letter saying the will offer shelter for my husband and myself ONLY for a few weeks time enough for us to find a suitable house for the family. we need to specify the kifs will join us later (2-3 weeks)...i have been told that the HO might doubt and reject this because they might think we will bring the kids and we will overcrowd the house.
2- rent a airbnb/hotel for the whole family for a month time and explain in letter that this is temporary and that we will rent asap....again i've been told this might not be accepted
3- we apply in march. try to find an estate agent that can issue a rent contract in february/march but the rental starts in june/july.... not sure this exists....again 'ive been told i have to have a house rent valid in march.
4-we apply in march .starting march ,rent a house (3bedrooms) and leave it empty and lose money.... this sound crazy!

thanks!!!!!
