With a good PM who can over see those things, it has the potential to stabilize a bit more then you would otherwise.I hope that helps, happy to jump on a call and discuss if that helps.

Find PMLs PMPs or buyers first and bring them deals, if you consistently bring deals they could eventually fund your flips 100% but they wont fully fund your first one and let you take off.

(I'm thinking adding 2 Beds and 1 bath, or maybe a master with walk in closet and an on suite, a large corner home office, etc. raise rent to $1,600)Needs: Roof, Siding, and Basement Work (potentially more space if the basement is redone, adding a bedroom and bathroom, rent at $1,800?) 

With careful research and property selection, it's possible to find properties with good cash flow potential.

Additionally, I do allocate a minor percentage of my net worth to investment with more growth potential, like land development deals.[...]Finally, what investment do you make to accomplish your financial goals?

There are also many more buyers in the market.

If it's in decent shape, I would do a couple upgrades to appeal to potential homeowners (adding window shutters or bark mulch outside, an accent wall, nicer light fixture in living room, etc. etc.)

If a buyer is offered a 2-1 buydown (starting at 5.25%, increasing to 6.25% and then to 7.25%) with all closing costs covered except for $3,000 (to be paid by the buyer) on new construction through the seller's preferred lender, and signs the purchase contract in April 2024, the house will be completed by the end of September 2024.

What makes the rental appealing to potential tenants? 

Buyers, realtors, lenders, contractors.
