I'm moving to Texas and have no U.S. credit history. I'm moving as a spouse of a U.S. National on a green card. I am looking at properties in the Houston area and have a 60-70% deposit. I'm looking for a 5-10 year mortgage.
I used to live in Canada and I have a good credit history there but was only there for 6 months. I don't have a great credit history for the UK due to redundancy back in 2012 and credit card debt.
I have always paid my mortgage on time with no interruptions and have payslips.
What U.S. Mortgages could I apply for?

You'd want a "ten year conforming mortgage". The large deposit is likely to overcome your lack of credit history, but you will still need to demonstrate income to cover the monthy payments. ...... Would you consider buying somewhere a little cheaper and buying outright for cash?

Thank you for you reply and info. I appreciate it.

I would consider it, however, it will not be enough to buy anything decent outright. I am able up the deposit to 80% by looking at slightly cheaper homes but still need the 20% as a loan or small mortgage. Can you even get a mortgage for 20%? Or would it be a loan?

A mortgage is a loan ...

The mortgage needs to be bigger than around $50k, otherwise the charges become "excessive" (as a percentage of the amount borrowed) and the bank won't be allowed to complete the mortgage because the regulators deem products with "excessive" charges to be "abusive".

The percentage of the mortgage (loan to value ration) shouldn't matter when the deposit is large - I am not aware that the mortgage percentage could be too small.

Be prepared to show paperwork that demonstrates exactly where every penny of that deposit originates.

Your best bet will be to go in person to a lender to talk face to face, rather than doing it online.

I don't know what the current state of interest rates are but don't dismiss getting a longer term loan (15 and 30 year terms are very common) which might have better rates and closing fees and allows you to overpay without penalty.

That would be my advice to the OP:- get a 15 year loan and make extra payments of principal each month to reduce the term of the loan bit by bit. That's what I'm doing.

I was doing it too, then my wife gave birth and it's been down hill from there...

A mortgage is a registered lien over real estate that provides security for a loan.

This And this But probably not this. Interest rates on loans get higher as the term gets longer, so the interest rate on a 10 year conforming loan will be lower than on a 15 year conforming loan.

Thank you all for your help. Your advice has been very helpful.

I wonder if getting a non-secured loan for any remaining amount under $50,000 would be an option?

Are there any mortgage providers that expats already out there recommend?

Often having checking accounts at the lending bank will save on various fees and closing costs related to the mortgage (and vice versa, having a substantial line of credit may save on monthly banking fees). We moved our accounts (Wells Fargo to USBank) to take advantage of this though we were looking to move them anyway because we didn't like the service we were getting.

I think the ideal loan type for you would be a home equity loan, which is a secured loan that is smaller than a mortgage, although you being in Texas might complicate or even prevent that because Texas has regulations over second mortgages that are much tighter than most states.

Getting an unsecured loan might be much harder because the bank doesn't have the security of the mortgage if you default and therefore is much more reliant on your credit history, which (lack of credit history) is currently you problem.

Wells Fargo is a major provider of home mortgages and secured and unsecured loans. Others have reported that they have been welcoming to new immigrants to the US, and they have many branches in Texas.

Umm how would that work exactly? Because at this point he doesn't own a home in Texas and therefore has no equity in a home against which he can borrow?

You can close a home purchase with a second mortgage (equity loan or equity line of credit) as part of the initial finance arrangements, or under the OP's scenario, where the "second mortgage" is the only finance secured on the home.

What this means in practice is that the bank disburses money from the equity loan to the seller, leaving a loan balance for the home buyer to pay down over the following years.
