If you go all cash will you have enough reserve funds in your SD IRA to cover unexpected repairs, and other expenses associated with owning the property?

We do have a stockpile of cash for unexpected circumstances and also have a monthly budget that is set aside strictly for unexpected problems.

But I would not use full comp on the stick build home.

Majority of the time in a commercial flip, there is an value add component, ie, u buy a vacant building, put in a tenant, then sell as an investment based off income.

We did find one that we spoke with yesterday, but could always use more recommendations.Long term (once we de-lead our house and move forward from this unexpected mess) we are looking to convert our 2 unit to a 3 unit, so would be looking for a lawyer that has experience with zoning/planning as well. 

Great idea, just as long as the house would cash flow after the cash out refinance, ALL expenses are conservatively estimated, and you keep some cash reserves to handle any unexpected capex, vacancy, etc.

Home warranties often cover very specific items/components (HVAC, hot water heater, etc), not structural, built-in systems (wiring/plumbing/ductwork) or aesthetic items. 

To purchase a $320K property, you would need to have a minimum of about $150K in the plan.As @Darren Eadynoted, any future expenses associated with the property would need to come from the 401(k), so one always wants to be conservative when maintaining semi-liquid reserves within the plan to cover any unexpected costs.That said, the ability to leverage your tax-sheltered retirement dollars into a secure asset such as real estate, and receive a higher cash-on-cash return for your invested 401(k) funds is a great strategy when approached the right way.  

@Rick Santos is usually have an attorney put them together, but I tell them all of the components that I want.

I had a property out in a semi decent area outside DC for a while and the A/C condenser was stolen 2 times, I mention that because there can be large unexpected costs in these areas especially if they are known to be high crime!
