Or use a credit card with a set completion date.  

I put my pics with alt tags and watermark on the MLS, to get more traffic and internet presence...wellllllll my silly little humans... 

I had impeccable credit, but now it's very poor.

No I do not see this as an issue, many have stated that back in the 80s, the credit card interest and auto interest was eliminated and both have growth and seen new heights in their respective businesses.

25% down or 20% down, my credit and income are solid.2.

I'd say that 25% is the prevailing number you should be thinking about but it won't take 5-10 calls to regional banks, credit unions, etc. to figure it out. 

We were lucky that we locked in during Brexit.We are in Denver, CO and have 790+ credit.

What should we look for in credit cards?

great job, not the cheapest, but did accept credit cards.

And this is coming from a guy who routinely melts down on my cell, cable, internet provider tech lines.
