Kyle,
Note other REO transactions to see if the lenders are repairing them.
You have to search for the answer to some questions. If your lender spent the $$ fixing the home, would there be a good or better chance of them recouping the investment plus, not just break even? Would it cut the marketing time to do so? Would it make economic sense to invest in the property or cut their losses? Does this market take a deep discount for REO's due to merely condition, or does anything with the 'lender owned' label get a significant hit in sales price vs. owner/occupied?
The best way to handle each property can change from situation to situation in the REO world. Tell them what you see, and what the market is doing. Be careful not to hit the home twice with the same repair, eg. landscaping and appliances in the repair list and under 'condition', then hit it again on the last few lines of the sales grid. Site/interior clean up is a repair list item in all cases except Fannie Mae REO's. Granted, the market will likely still discount the home for it's needs, but with Fannie Mae you just can't put it in the list. Do still consider it when you calculate your 'As Is' value.
As far as appliances go, 99% of the time I don't call for replacement of them in REO's. That is a decision for the new buyer's lender (if applicable) to require. If the stove, hood fan, and dishwasher are gone, I consider that vs. my sales comparables in the grid. Yes, it affects the value, and it is reflected in the final reconciliation. My repair requirements are items that are necessary to bring the structure to equivalent 'average' condition in comparison with it's neighborhood. ie. roof, paint, carpet, HVAC, cooling, faucets, drywall repairs, etc. Concentrate on the items necessary for structural safety and soundness, and those that would allow your market norm of financing availability and reasonable market acceptance. (usually conventional guidelines). If the walls are showing heavy soiling, scuffs, crayon art, etc., call for repainting. If it's average wear and tear, I make no requirements. Remember, the REO label will very likely still wear heavy on your subject's value. It's not necessary to turn it into 'house beautiful' unless your market would absolutely shun it otherwise.
The basic thing to remember is the lender/client is looking to you to give them the skinny on what would be the most economical, quick way to get this asset off their books and get back into collecting payments and interest. They typically want to lay out as little $$ as possible unless absolutely necessary. Do be aware of safety concerns and liability issues. If the roof is caving in, and this is a real good candidate for As Is, at least let them know to provide temporary support so it won't potentially fall on a looker and hang them with a lawsuit. If you really think the storage shed is on the neighbor's property, let them know and suggest a survey. Be careful not to make the absolute determination that there is an encroachment and call for the removal. Remember, you're not a surveyor.
Hope this helps. Please feel free to PM if you'd like.
