I agree with Bryan. Based on your numbers, the value is $100K AFTER repairs, yet she currently owes $95K. How much are repairs? What about closing costs? Other incidentals?
When looking for Sub-2 properties, it is usually best to find one that has at least 30% equity. This is not always the case, but can be used as a rule of thumb. It all depends on your exit strategy. If you plan to keep the property and rent it, 30% equity is good, but if you plan on flipping it to another investor, you will normally be out of luck, as they are looking for the same 30% equity.
If you can get a property for 40% equity or more, after all expenses, that would be a great deal. If you plan on making it your personal home, a 25% equity might be a great deal for you. But, you have to remember to add in all the costs associated with the closing before you think a deal is good.
It also depends on how your market is trending. I did a Sub-2, where the property was worth $105K and I got it for $59K. I put $5K into fixing it up, then turned around and rented it out. Since then, the property value has fallen $35K, so that property is now worth $70K. Part of the $59K I paid was to bring the loan current, then $8K to the seller. I currently owe $39K for this property, as I bought it SUB-2 two years ago.
Another thing you need to identify is the terms of each loan. If the seller has a 15 year lease with a 6% interest rate and still has 9 years left on the lease, then you are still paying quite a bit in interest. So, you have to have a strategy ready for those scenarios. The above scenario is the one I faced. In my research, I misidentified the number of years left to pay off the loan and the interest rate.
I still believe I got a good deal, but I am running at a $50/mo loss on this property because the loan is 15 years, not 30. I am re-financing it in the next 3 months and will be able to change that $900/mo mortgage payment (which includes taxes) down to a $200/mo mortgage (not including taxes).
I have a great tenant who is willing to purchase, if I ever decide to sell, also. Not only that, but both the tenant and the previous owner have sent more business my way because I treated them right. I could have decided not to give the seller any money at close, but made the decision that it would not hurt my position and it would benefit them. The current tenant owns a landscaping business, which has been severely hurt by the lowering house values. More people are doing their own landscaping instead of paying for a professional. I use him on my properties and he has given me a much lower rate due to the number of properties I use his services on and due to him being a tenant.
Now, a lot of what I have stated doesn't address your question on SUB-2, but it does help address other issues concerning RE investing. RE investing is a people business, not a property business. If you treat people right, then your business will grow. If you don't, it will be much harder to grow your business.
I hope my ramblings help.
