(as long as you aren't being charged by the job) Do your homework on load bearing vs non, header spans, carrying load to foundation, etc and you can save thousands. 

I have a business with 5 people (and a 6th and 7th who aren't in the core 5) that spans across three states, and ever expanding into others.

I respectfully must disagree with you.First of all, in the United States at least, the buyers and owners of manufactured homes span a wide variety of the economic spectrum.

acquisition: $1.2M, 1,600 SF single family house development costs: $1.3M (inclusive of all construction, consultants, permitting, bank fees / interest, prop tax, insurance, utilties etc). sales costs : ~$250k (incurred upon sale only - broker fees, transfer tax, staging, closing costs)time / carry:acquired Jan 2015expected completion May 2017. finished product: 2 new construction luxury condo units, 2 floors each:Lower unit - 2,250sf - 3 bed, 2.5 bath - one car garage spot (side by side) - deeded entire backyard (approx 1,000sf)Upper unit - 2,250sf - 4 bed, 3.5 bath - one car garage spot (side by side) - two large decks (master bed and living room) plus deeded ~500sf roof deck with nice views spanning bernal hill to sutro.

Perhaps, if there is only a 5 year life span left, you want to do the replacement reserve in 3 years, and set aside more every year.Naturally, if the HVAC equipment is only 10 years old, you set aside less each year, because you have more time (hopefully).At some level this is a guess.

Since most syndicated offerings have a life span of 10 years or less, this works very well in this context.Of course, tax benefits aren't the only reason to invest in syndicated offerings, and how the sponsor treats tax implications shouldn't be the primary deciding factor when choosing a sponsor to invest with. 

But could you do it this way, in a 4 Year time span ?

In the span of less than two months i had watched my life systematically unfold before my eyes.

In addition to keeping current with regular maintenance, know the estimated life span of certain building components and that of appliances too.

It's gone from 300K to about 410K (comps) in the span of about 2.5 years.
