I'm not sure about the loan qualifications, but I'm sure you'll need an income source (and probably some money in your CPF).

You can hold title as: Joint tenants, Tenants in Common, Tenants in Business Partnership or as Community Property with the Rights of Survivorship.I am not sure about easier qualification for loans dependent upon the method of holding title. 

If not, then yea, they may require a pre-qualification letter from your bank but if not, they should qualify you before accepting the offer.  

The downside of having a sole member LLC is that since my wife has w-2 job, her portion of income won't qualify for mortgage qualification which means less leverage for us.  

Qualifications: At least 1 real estate deal purchased since joining BiggerPockets ProA willingness to share the ups and downs of your journeyA fun personality (and the ability to rip on Josh a bit… 😉 )A fast internet connection and decent microphone (we can offer suggestions if chosen.)Now, obviously we can’t feature everyone.

shared - but I wouldn't count on it to happen to you.If a potential tenant has an ESA Pit Bull and your insurance specifically does not allow pit bulls, put that in writing in your qualifications.

For you, as the Buyer, there is no difference between Seller Financing and Bank Financing, except that you would bypass the loan qualification process that the bank loan would involve.You buy the property, you own the property, the Seller has a lien on the property which he will foreclose on if you stop making payments on the debt that you owe him.  

I am sure I can figure out how to manage the HOAs, but is there additional qualifications or designations other than having a real estate brokerage?

One thing I learned pretty quick is my LLC which just does buy and hold properties does not qualify for a Solo 401K yet, because it does not produce self employment income, paying myself as a property manager I was told would not pass an IRA audit, so Im looking into a SD Check IRA or sometimes called a SD IRA LLC, which gives me some of the benefits of a Solo 401K without the qualification requirements.Good luck

So with that premises in mind:1) I would put your qualifications in your AD.
