You should be more concerned with cashflow than with what proportion the taxes represent of your expenses. 

Frayser et al I took properties back there and its a freakin nightmare of epic proportions.. it was mainly the GB marketers that hooked up with terrible US partners that sold that crap. 

This is just my opinion, but the mold thing is blown WAY out of proportion.

I buy sufficient materials for them to start work and only pay a proportion of each aspect completed e.g 75%.

Even though each investor will have equal profits proportional to the % interest contributed to the loan.

The additional space will probably fail to yield a proportional increase in value/final sales price...That being said...

A bit of exposure to each is wise, just adjust what proportion of your overall portfolio you allocate to each based on opporunity.

When you take over, be sure to have efficient bulbs installed in those common areas (either compact fluorescent or LED).

Dollar for dollar, multifamily homes tend to generate more in rent as a proportion of the purchase price.

All that really matters is YOUR capitalization rate that is a blending of your debt constant and required yield on your equity in whatever proportions they will be used to capitalize the purchase.
