@Eudes De leon I looked their google briefly....it seems 3 resin and 1 comm’l is fine, but....there is a little more to it,  not laid out in straight black and white.It has to be in a predominantly residential use area, the commercial component doesn’t “over power” the residential use/characteristics, etc...as @Chris Mason says, the actual determination is made by the fha appraiser.

Everything else inside the dwelling structure is a structural component that would be depreciated along with the structure itself on a 27.5 year schedule. 

When we partner up on flips we look at it as 3 different components: 1.

What are the basic component of a good insurance policy?

You can take participant loans from the 401k, you don't need the additional expense and administration of an LLC to have checkbook control, and there is a built in-Roth component if you'd like to make tax-free investments.

Thank you for pointing out the cultural component as well!

Did every major component and appliance get replaced during the latest renovation? 

It does require self-employment activity, but has a lot of advantages: Compared to an IRA, Solo 401k contributions limits are roughly ten times higher.There is no custodial requirement for the 401k.You don't need the additional expense and administration of an LLC to have checkbook control.There is a built in-Roth component whereas IRAs are either traditional or Roth, not both.A spouse can also participate in the same Solo 401k plan.The Solo 401k has additional tax benefits over an IRA when investing into real estate using leverage.The penalties for prohibited transactions are less severe, though it's best not to utilize this benefit :)

There have been cryptocurrency transactions recorded via blockchain, first one done in Vermont a few months ago, but there are so many components in a flip that using a cryptocurrency is not commonplace or practical just yet.

Also they won't do anything with a residential component unless it is incidental to the operation of the business, like an apartment for an on-site manager for a hotel.
