I've successfully managed multi million dollar assets for investors of unit sizes from 250-980 units within multifamily.

They will see some value from additional lot size if they combine to their property.But I don't see how you could get any write off.

I've hunted for information and have only read that impact fees will be correlated with the size of the 1200 sq foot adu compared to the 1500 sq foot front house.

On the flip side a downturn it could mean more renters and less buyers.What is the HUD fair market value for rent of your sized property? 

There's no standard formula, but typically all money is treated the same and if one partner is doing the majority of the work they should be compensated by either through fees or an out sized % of cash flow compared to their equity over a certain return threshold. 

Account Closed  Also, what size properties are you going after in these markets? 

I think you have to get a PM that manages units of your size.

It all depends on the location, type and size of property Fisrt step is to meet with the city to find out if there are any code issues and non-conformities.

I am sure this varies depending on the size of the job like if you are using 1 GC or a few subs.

Plus if you over size them a bit and dont do huge spans then the city usually doesnt ask for calcs anyways.
