Worth area where you can easily find move in ready 3/2/2 homes for less than $300K with strong rents and low days on market.

You want to be sure the parking area and/driveway is also not too steep.Also, as evidenced by the last 10 days in the area, be wary of anything on or near a water source or low bridges and such to get to it.

I'm also seeing opportunity in people "locked into" their low rates, but having a life circumstance changing their needs.

Are you lending out funds? 

From a servicing and reporting perspective - if the lender does not report to credit and they REQUIRE an LLC to fund, then the parent servicing entity most likely will keep your business/investment loans separate from personal credit.

If you don’t care about cash flow year 1 you can go down as low as 6% cap rate and still break even.

I'd find or list the land and get a partnership. you could not even have to self fund the construction. if someone buys the land it establishes the value. a lot won't give you much value for land unless you split it out on the original transaction.

I’m willing to give a pretty significant interest rate for a private lender who is willing to fund this deal for me.

If I can put down 5%, retain a lot of my savings/emergency fund, and pay less than I would renting, then it's a win. 

You can use a free CRM (or low cost) for investing like HubSpot and not make a dent.
