It's a great returning property. 

Do you allocate expenses between business and personal or is there a threshold where you can write off the whole trip?

Could it be considered piercing the corporate veil if the mortgage for the property is in your personal name but the deed is in the name of the LLC? 

And ensure to not intermix the business and personal between the two. 

Work with a CPA familiar with SDIRA tax implications to plan accordingly.Private Placement Memorandum (PPM) review – Ensure the syndication allows for IRA participation and that the deal structure aligns with IRS rules.Direct Purchases with Non-Recourse FinancingLender requirements – SDIRAs can only use non-recourse loans, meaning the property secures the debt, and your IRA isn’t personally liable.

If you are looking to be very active and run like Mid or short term rentals yourself, or do flips, then you can, but this does not come without risk. if you are looking to pull money out and put it to work in other real estate so it can appreciate over time so you have a larger base of assets that are paid down or off in the future with some cost now, then I do think that is possible. 10% returns as a passive investor, especially in the first couple years is not likely. 

Is the landlord required to return the full security deposit to tenants ( or partial security deposit with itemized list of what deductions were made) within 21 days? 

Most of my returns are around 5% a month, with some at 8%/month.
