I bought my first househack last year, and I am getting ready to make an offer for the second one.

We have a dire housing shortage in Milwaukee, so the market is competitive and everything worth buying sells quick and usually with multiple offers. 

However, I would like to gain some practical experience in the world of Notes as well.

2) What protective measures should I consider as a buyer in a seller-financed deal to ensure the offer is as efficient as possible?

Buyer agents will reduce in number because many offer the same services.

I work with many fresh grads and even an offer letter can get you a conventional mortgage.

I've shifted my focus from textbooks to spending quality time with my dad, who hasn't been feeling well lately, and I'm aiming to build up some savings through investments.Now, I don't have a car, but I have a friend who works nights and has kindly offered to give me rides anywhere between 3am and 4pm.

It's just about having the right team in place where you can identify them and get offers submitted quickly and solid contractors that can give you realistic quotes so your financial forecasts are accurate. 

Something without a HOA is best.4) find a local group and go to some of their meetings (if you are buying locally)5) contact a realtor who works with investors and look at a few places after you've run the numbers and be prepared to put in offers and follow through
