I applied for funding on COGO but the interest rates were to high as well as the points. 

I feel like I only need to incorporate DSCRs, NPV, IRR and of course growth rates (both expense and rent). 

ActualAs an example of the problem of Rentometer data, I looked up four recently rented properties on the MLS and compared the Rentometer prediction to the actual rental rate.

From a cash flow perspective, you’d really need to think long and hard about the cost of leveraging these properties, especially in the current rate market.Yes a bigger purchase price might mean a greater potential of higher gross cash flow and appreciation, but that cash flow might get eroded fairly quickly if these moderate interest rates are here to stay.- REI CPA from CA

However, if it needs that much work you are probably better off going with a hard money loan and then doing a rate & term refi once rehabbed.

Does it make sense to pay a premium for cheap interest rates with seller financing, or would it just be better to put 25% and forget about my 15% criteria and just go for distressed sellers and just get a commercial loan. 

To address this, we agreed that I would work in the business for six months to verify the financials, which so far align with his POS system.My main issue is that at 23, I don't have strong financials to get a conventional loan at 75% LTV with a ~7% rate, and the seller's lack of financials complicates bank approval.

The sales price is contingent on the property appraising for the agreed-upon value in that given timeframe.The goal of subject to, for the buyer is to take advantage of your low interest rate, maximize profits to pocket as much cash flow as possible, and then, however, in many years be able to cash out refinance and pay your mortgage off in a lump sum to acquire full rights of the property.

If I remember correctly, the redemption rate in CHS county is something like 80-90% and the interest that can be earned is capped.

At that time, the builder will pay the accumulated interest along with the principal.We have discussed a few different options to structure this arrangement, assuming an interest rate for interest-only loans with monthly payments is 10%:Option 1: delayed interest with a rate of 12% (interest rate is 2% higher)Option 2: charge a lower interest of 8% then profit share (need to determine appropriate % split)Any other thoughts on how to structure this arrangement?
