As an individual landlord, especially one managing remotely, it might be challenging to secure similar terms.Payment Trust: Vendors may also be hesitant to extend credit or prioritize someone they are unfamiliar with, particularly when the owner is based internationally and payment assurances are less certain.Real-Time Issues: Handling urgent maintenance or unexpected issues can be cumbersome without a local presence.

Additionally, income from an active business inside of a retirement account will be subject to UBIT (unrelated business income tax), so be sure to consult with a qualified tax professional about the implications. 

If tax returns and DTI is an issue look at private institutional lending. 

How are you collecting a deposit, or putting holds on credit cards, for your STR direct bookings?

@Alanna ThomasIf you financed your property through a lender that escrows for your taxes and insurance - that stays in place regardless of what you do with the property (ie rent it out, etc).  

Property taxes are paid by parent A and parent B.The current deed states tenancy in common between parent A and parent B as married, and aunt A, unmarried woman.

So gift the proceeds tax free or put my name on house and sell it?

It will increase tax rates on STRs from residential to commercial, so from 6% to 28%. 

So my question is, can I take out a line of credit against that equity to help fund my next purchase, or can I not take a HELOC out on an out of state investment property?

If you are buying in your own name, then obviously you won't have this as a formally separate entity.But the bookkeeping will be so much easier at tax time if you set up bank accounts for the rental property separate from accounts you use for your personal expenses.
