Even if you get a higher rate, you don't want a HELOC loan stuck in a long-term investment.

Your property listing can also be a great way to lay out qualifying criteria (i.e credit score minimum, and require a co-signer if lower).After conducting due diligence into a particular tenants situation, and you decided to proceed with an application approval, you could require a higher security deposit. 

Many of the higher priced options offer stronger networks than they do coaching, so you're really paying for the network more than you are anything else.It sounds like you already have some knowledge of real estate from your past experience. 

My guess is that LTV would be low and the rate would be higher.

I do it for a living and finance about 200 of them a year for other flippers this is why i have a pretty deep understanding of distressed assets and the taking advantage of those that might no realize they are paying 3X what a property is worth.. if your paying market price or maybe 10% higher for the owner finance i get that I do that and agree with that thought process..

The expectation should be for higher returns to compensate for the illiquidity, but it's part of the deal. 

Deduct NEW property taxes after you buyDeduct home insurance costsDeduct maintenance percentage, typically 10%Deduct vacancy+tenant nonperformance percentage(we recommend 5% for Class A, 10% Class B, 20% Class C, good luck with Class D)Deduct whatever dollar/percentage of cashflow you wantNow, what you have left over is the amount for debt service.Enter it into a mortgage calculator, with current interest rate for an investment property, to determine your maximum mortgage amount.Divide the mortgage amount by either 75% or 80%, depending on the required down payment percentage - this is your tentative price to offer.If the property needs repairs, you'll want to deduct 110%-120% of the estimated repairs from this amount.Be sure to also research the ARV and make sure it's 10-20% higher than your tentative purchase price.As long as the ARV checks out, this is the purchase price to offer.It is probably significantly below the asking price.

CoC just about breaks even if I assume rents are on the higher end of the spectrum. 

I've been told the higher deductible also effectively killed FHA financing.

You would likely get higher daily rates by renting out the 3 BR.
