Cost vs.

Then do a 'seismic strapping' to aid in halting further movement.IMHO this should cost closer to $20,000.

Analyze potential deals by estimating the After Repair Value (ARV), repair costs, and total expenses. 

The seller will lose some rent, potentially incur costs to evict, possibly costs to clean out the units depending on your sales agreement.

You’re on the right track—build awareness of costs where it directly impacts their role, but don’t overcomplicate the program with factors they can’t control.

Be conservative on your rehab budget, rehab timeline, holding costs, etc.

Closing CostsMake sure you also budget for closing costs, which are a collection of fees and payments made to the various parties involved in your transaction.

You could also get a line of credit for about $150k (you should be able to borrow 75% of the value.)The reason I suggest this is…1) you save $40-$60k in selling costs. 2) you have a lower blended interest rate (2/3rds at 3.25% and 1/3rd at 7 or 8% instead of the whole $500k at 7 or 8%) saving you another $1k/mo in interest. 3) you only pay interest on that $150k when you actually use it, not from day 1  Unless you hate this property, or want to buy something you can’t afford without selling, that would be my plan.

Two notes:1) The solar company may give you the best interest rate.2) If the power goes out, you still don’t have power if you have solar. 

Given the latter costs, a corporation can be the best solution only if you buy multiple properties.
