you can also hedge  your bets by maxing your employer 401k match and max your roth now, giving you options later on, because you never know.Your penalty for failure is less., if worst case happens, and you crash and burn, at your age, overcoming a bankruptcy or having to walk away from a property, you can rebuild your financial picture well before it's a more significant part of your daily life when you are older, and might need to leverage credit for the bevy of financial demands that come later in life. when you do have kids, a house in the burbs, 3 cars, and college payments....etc.Your lack of experience is the same as anyone else getting started, like me, twice your age. 

Confirm that the provider has experience with the particular investments in which you intend to invest your retirement funds as you very likely will have questions in terms of the mechanics (e.g. how do you invest in real estate, etc.).4.

I would recommend that you get an auditor or mechanical engineer to give you some suggestions.

How did they get started, what way do they invest (Buy/Hold, BRRRR, Flips ETC) what they learned, what worked for them, what failures did they have that you can avoid? 

The exterior, sure, but not the basements (unless there are mechanicals / water issues to deal with).Are you buying this under market value?

That way you can size up how frequently to expect repairs.I would also say choosing a PM is about the same as choosing an auto mechanic.

The size of support corridors, mechanical storage, laundry, etc is widely variable.

For a six figure discount from your original offer, it may be worth buying it as a two flat and taking the time, effort, and money to try to get that garden unit certified but there's still no guarantee that it could be done; to me a $75k discount isn't worth that risk of failure unless you think the numbers could still work as a two flat (after paying to have the first floor duplexed down).
