With weather getting more and more unpredictable, it just seems like something a tenant could complain about that, even if you didn't do anything wrong, could land you in hot water. 

Airbnb handles the payment so I don't worry about it and I've found that the typical tenant that is willing to pay 2x the LTR rate is going to keep the property in good condition.

However Property tax's some of the lowest in the coutnry and property maintenance same thing if you buy a stucco home with a tile roof.No real major weather threats like many markets  IE hail storms wind storms etc.. can get windy but thats common.. 

What are the most promising alternative lending strategies for financing RE developments given the rising interest rates and tightening credit conditions?

You might consider giving a notice to the entire building that you will be doing a walk-through on a certain date to check the condition of the property - you have a right to maintain your property and access all units if they are home or not with proper notice.Also, make sure that your notices have a person named as UNKNOWN OCCUPANTS listed.

The condition, age, and future capex issues are more important in my opinion.

We recognized market conditions were optimal for a fast flip, and our ability to act quickly minimized holding costs while maximizing profit.

Though, if you want to make changes with newer mobile homes there may be some restrictions (i.e. age, condition, etc.).

Anyway, after appraisal we were able to insured the property with Universal company, I recently got a letter that my policy was going to be cancelled due to the condition of the roof.

It was priced at $105K.... in fair/poor condition... it was still an amazing deal.
