You should vet the company to ensure they have the resources to pay the rent.You ALWAYS do background checks on the people living in your property because if you let in an axe murderer and they harm someone, you are likely to get sued.Whether or not you charge an application fee is up to you.  

Quote from @Jason Williams: I have an investment property that I own outright (in my personal name).

Quote from @Joanne Bragg: Yes, for sure, just as the others stated you'll have to get an attorney to get you out of this mess.

Quote from @Karen Kwak: I just purchsed a property under series llc.

When I call the company what questions should I ask in order to know what I have to know if whether I would want to buy or wholesale (I've done neither ever) but just to get kind of a script or advice on what to say.

I'll work with an attorney to assist with drafting that.Q2: Yes, I'll talk to my CPA but we'll most likely hold the property for at least 1 year under the LLC given our timeline to design, permit, build and sell the property, meaning I should avoid short-term capital gains.  

If the LLC is disregarded, meaning the property is owned by the LLC but it gets reported in your personal taxes and you file a joint tax return, than you (or rather your joint tax return) is the tax-payer for the property.

I have a Duplex I was doing a long BRRRR on.
