They have maintained their beautiful historic architecture and would be a great investment for any serious investor because they are also very close to each other which would make them easier to manage if all are bought together. 

Architecture and engineering along with other things like (title 24, etc etc ) 3.

High end investment property: Christopher Architecture and Interiors and Narnia Construction. 

We are an architecture firm here in South Philadelphia, that specializes in this type of work, specifically for investors.

Do I know my total costs: Construction costs, lending costs, miscellaneous holding costs, site approvals, permits and design/architectural costs?

Soft costs are:  architectural, engineering (structural, mechanical, plumbing, electrical and civil), real estate taxes, appraisal, survey, insurance, permit fees, miscellaneous, title, legal, and construction interest. 

I am thinking about converting detached garage to rental ADU in tacoma area, I am looking for architecture recommendation to draw up plans and file for the permits, thanks in advance. 

I say this as someone without a college degree, that has done IT engineering/architecture consulting for some fortune 100 companies.

Over the past year, I have got drawings (architectural, civil, structural, mep) done to expand this property for my business use.I want to turn the 2400sf warehouse into our office, add 5000sf to that for our warehouse, and add 7000sf building for another warehouse to rent out for now, and eventually expand into.Now that we’re getting to permit stages, I’m getting “childish” feet, and need help analyzing the numbers.So, my build cost on the building we would be using is 640k.

I looked into it, but backed off.Reason: I was looking for opinion from contractors whether to go for ADU or JADU, but contractors needed me to get the architecture of my choice…..would revisit if there is ADU contractor who provides comprehensive package, architecture, city-approval etc....Open for suggestions.Good Luck..
