Why do you need new furniture? Presumably you lived somewhere else before and had furnishings? Were they sufficient? If the issue is just that you now have more space and so have some empty rooms to fill, that is a "want," not a "need," which mean you can take your time in finding the right piece for the right price. [Note: you may actually have a need here. But I have noticed a tendency in some people to believe that new house = new furniture to make it all pretty and perfect at once. If that is what is driving you, challenge your assumptions about what you actually need.]
I would never buy new furniture online without inspecting it in person, especially if you are looking for higher-quality pieces. There seems to be a significant split in furniture, between low-priced crap and high-priced decent stuff (if you are looking at something priced in-between, I would assume that it is simply crap with a higher price tag). Your best source for reasonably-priced quality furniture is the used market -- estate sales in particular (many of the older generation bought high-quality furniture designed to last a lifetime, and now their heirs don't want it), but also garage sales, Craigslist, auctions, etc.
Or if you need something now, just go to Ikea and get something cheap. Your pictures are basically wall-to-wall wardrobes -- there's nothing special about that, they are simply utilitarian. So buy something functional and be done with it. Save your "fine furniture" budget for specific pieces that you will notice and love every day.
