How to choose a design?

[Tio Sam]

Hello everyone,

This is my first post/question. I recently purchased a property with the intention of doing a fix/flip. I'm a contractor based in Maryland and DC, so the renovation aspect is well within my expertise, having done numerous projects for other developers and general contractors.

However, I'm facing a challenge when it comes to choosing the interior design elements, such as bathroom tiles, colors, sizes, fixtures, etc. I would love to hear how you all approach this process. Are there any apps or tools that you find particularly helpful? Should I consider hiring a professional designer, even though my budget is quite limited?

Any advice or recommendations would be greatly appreciated. Thank you in advance for your help!
