emwithme that's pretty similar to what I did, except that I advertised it on the dreaded gumtree, didn't get nearly so many enquiries, but still...quite a lot, and I sent them all a form with pretty much the same questions as yours by email in response. Except I specified that I would need previous landlord's reference, failing which, as a result of not previously being in rented property, a current employer's reference. not a reference before viewing, but simply making them aware that it would be a formal arrangement, with references and a six months SAT required and me complying with all the legal requirements.
As soon as I sent the form, most of them simply disappeared, although kick-off man sent me pointless stupid emails back arguing saying "did I really expect a reference, he wasn't used to renting property and didn't know what to do, was I sure I needed a reference for him to rent it, could he just give me his employer's details and phone them myself (I would phone anyway, but no, I'm not going to chase up references for a tenant in the first place).
I thought I was going to rent to one of the single men, who claimed to be getting divorced, because he viewed it, seemed fine, said he would complete the form and provide references, and so I texted him to say he would need to put the first month's rent plus a month's rent as deposit into my bank account and sign the lease. And he went quiet, then texted back a couple of days later to say he had changed his mind.
Same thing with a single woman, except she just disappeared without explanation.
I'm certain its nothing to do with the property, as its a new build and everything in it is brand new.
It seems to me that most of the prospective tenants seem to want it all done very informally.
