Asking for additional credits could easily ruin this deal.

I was told the investor pays to lease out the entire flat for 6-12 months and then sub-leases the individual rooms for a profit.

The closing attorney or Title company may be the determiner for an answer and usually at this point in the process as an agent I'd defer to them.As an investor, I think I'd want all this squared away before closing so maybe check with the attorney/closing company.

I'm new to the forums (first post), although I've been lurking for a minute.  

If you are looking for loans on real estate or a business lenders don’t necessarily care about the credit history of the LLC - they care about the performance of the asset and your creditworthiness since you will most likely have to sign personally.I have established multiple LLCs just days before closing on large loans for different assets, those particular entities barely existed and the banks did not care.If you are talking about pulling a business line of credit (like a HELOC, but against your business equity) then the banks like to see some history of revenue.

Be ready for a huge amount of information at your finger tips.

This is a big jump for you, but it's possible.

@Ilya G.Hi, how much do you need for a down payment?

For small properties such as a duplex I don't bother with making sure the two delivery points are registered with the post office.
