You can also consider selling the properties to the tenants on terms.

You could go to work for a remodeler too perhaps giving bids, selling service or see if they will train you to be on a crew.You could also go to work as an ISA for one of the big wholesalers. 

@Jim Rice Yes are you trying to create notes, do you own some and want to sell them or you trying to broker notes?

No but keep track of those repairs as it will add to your cost basis when you go to sell it and have to pay capital gains.

Does anyone have experience buying properties for cheap from land banks, renovating them, and renting them out/selling them?

As you are partnering with your sister, have a legal document drawn up as to what happens if one of you wants to sell and the other doesn't, how expenses will be split along with money you are putting down, borrowing, profits, etc. 

Because there have been such significant gains in the markets this year (unless you are a bond investor😬) fund/asset managers and stock traders will likely do some portfolio rebalancing in January, selling winners, and locking in tremendous 2024 gains.

The one guy I spoke with said they make money only when they sell to potential investors and they only sell new construction homes that are usually pre-leased to buyers (currently they are building in Texas state and Missouri State).

Some lenders will fund 100% of the deal + renovations if you are experienced.Wholesaling is possible but be mindful that it is a business, you don't make any money until you can persuade someone to sell their house and then to find a buyer.I personally think its easier to be an agent, still a business but there should be people teaching you and you have more of a reputation when talking to sellers.

You can get eaten alive in the Baltimore market by people selling you Class D properties "dressed up" as Class B.
