This is the section I have in my lease APPLIANCES INCLUDEDStove and Refrigerator, DishwasherLandlord is responsible for repairs to appliances listed above unless otherwise stated here: Dishwasher will not be repaired, If tenant would like to pay for dishwasher repairs they may, upon written permission from Landlord, all repairs or replacements will become sole property of the Landlord and will remain in the unit when Tenant vacates.Tenant will be held liable damage to any appliances beyond normal wear and tear. 

Unless this is owner occupied you aren't going to be able to do much better than 20-25% since it's multi family..... exception being you have the funds to buy cash, do the repairs cash, and then do a cash out refi once repairs are completed.

Starting now also might allow you to classify things more as repairs than capital improvements.

It takes into account the repair cost, the holding period, and the after repair value. 

Unfortunately, now I got an "order to repair" from the city (and not complying will result in fines) but repair is out of the question - simply not worth the cost.

Even if you need cosmetic repairs, that may cost more than $2M.

However, he refuses to repair it at his own cost.

There is just a little less room for error when dealing with a smaller park as you don't have as many lot to absorb a vacancy or an increase in water usage(even if you can collect)..or some repairs to do etc.Good job on negotiating them down so far...for me i will still have to go lower and look something like this....200*18*12*.5/.1=216k purchase priceI prefer to pay lower than this based on a smaller park and limited upside potential based on your observation of market lot rents.  

No other liens.Estimate $75,000 to repair house, trailer and barn/yard for a flip.Owner is open to owner financing.
