I definitely plan to have cash reserves for those unexpected costs that might arise.

We unexpectedly (and now thankfully) ended up in the Vet Park / Sunset area and have been AirBnB'ing our "extra" unit with amazing results thus far.  

well to me if that component was not on your original scope of work and you never touched it  .. this should have been caught at home inspection. 

I am completely shocked and surprised by this action as this was unexpected. 

for the extra cash you keep for maintenance and capex issues that might come up unexpectedly.

(It’s a 1021 sq ft box), + realtor/holding/closing/unexpected costs...

To an underwriter, that means that your monthly liability would need to increase in order to cover "unexpected" expenses.

If you're self-employed, the Solo 401k plan will likely work better for you.A few Solo 401k benefits: Compared to an IRA, Solo 401k contributions limits are roughly ten times higher.There is no custodial requirement for the 401k.The Solo 401k can allow you to borrow funds from the plan, unlike with IRAsYou 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.

@Dmitriy Fomichenko in regards to 'converting' traditional funds over that are already in my SOLO401K to the ROTH component, if those 'funds' are say a rental that I paid 100K for, do I need to get an official appraisal of that property to covert things?

The second thing i suggest you focus on is funding. 50K is a great amount of money to start with, however, it’s always better business to leverage other people’s money so that you have some capital to fall back on for the unexpected.
