Private strategic acquisition - homebuilder -> homebuilder - How to model?

I am working through modeling an acquisition (similar to DFH/ Coventry acquiring MHI). 

I have been asked to model the acquisition. “Simply”. The deal is in the early pre-LOI stage so available information is dirty. 

My employer is looking for a tool to quickly get down to a range of rough order of magnitude pricing based on several factors. Extrinsic multiple valuation and likely usuing an ROA hurdle of some sort. 

I am new to homebuilding and this sort of acquisition. I am a real estate developer. Ground up. Manage acquisitions through to disposition. I don’t yet appreciate the lens this employer is  looking through and we have not been able to sit down so I can understand how they want the input, analysis, and output shapes to look. 

Does anyone have experience with anything like this? I would greatly appreciate any help I could get. I can model anything with an understanding of the inputs and outputs. My new boss wants me to read his mind and I was hoping to knock it out of the park. Need a little help.
