I did a complete cosmetic rehab. new bath and kitchen, paint, flooring and recessed lighting.

If you take @Kevin L. s proposition, my little 16 SFR business should have PM software, commercial office space, HR, Legal, Marketing and maybe a corporate jet and helicopter. 

Also leading to the master bathroom remodel and new hardwood floors!

My wife and I just bought a 3-family in Marlborough, MA, there is knob and tube all over the place, and we are planning on moving into the first floor. 

Also the CAPEX is imaginary, since the house has all new systems - new roof, new HVAC, new plumbing, new WH, new wiring, new floors, new kitchen, new bath - but I tossed it in there just so you'd have a number.

SO when a tenant rents a space and fixes it up to be a restaurant, the improvements they made get the new 100% depreciation for 1 year only (then 80%, then 60%, onwards) So I’m afraid this law change will have no effect on you depreciation wise."

With MHP's becoming so popular right now, if the market doesn't drop out, they will be even more popular, and the ever consolidation of the industry, cap rates are compressing because more people are getting into the space that have lower return objectives and are fine with lower returns because they are placing their capital that has historically earned them lower returns than what they are used to based on never investing in this asset class.  

We plan to enter the multifamily space, purchasing properties with 8+ units with the potential to add value and attract higher quality tenants. 

Here's my question:I liked the house because of the space available to build.

Maybe you do a house hack with other nurses on opposite shifts so you aren't even in the space that often at the same time.
