C# linq similar range list

I am creating similar properties list.

I have to look for the 4 similar range properties in the list.

• If the price is $400,000 then I have to find 4 properties of $400,000 price.

If the 4 properties could not be found then

• Sort the list high to low and find the remaining properties from the list.

If there are no same price properties then

• Sort the list from high to low and get two properties from the list

• And again sort the list low to high and get the 2 properties from the list

In order to find the same price properties

var properties = props.results.Where(x => x.Price== price).ToList().Take(4); 

High to low list

var highToLow = props.results.OrderByDescending(x => x.Price).ToList().Take(4); 

Low to high list

var lowToHigh = props.results.OrderBy(x => x.Price).ToList().Take(4); 

The problem is

When there is less than 4 properties found from the same price properties

var properties = props.results.Where(x => x.Price== price).ToList().Take(4); 

Now I am sorting the list High to Low and finding rest of the properties from this High to Low list.

var highToLow = props.results.OrderByDescending(x => x.Price).ToList().Take(4); 

How can I combine the list ?

Has anyone done something similar to what I am trying to achieve. Any help or suggestion would be appreciated.

Thanks in advance
