I have plans of purchasing a mobile home to rent but I have one problem.

See what documentation they require for approval.

Loan investors have a protocol and procedure to be followed to make sure people really need a short sale and aren't just bailing on an upside down property at the owner of the loan's expense,; to get as close to FMV as possible; analyze whether a foreclosure will net more money;negotiations with junior lien holders; mortgage insurance providers approval; etc, etc.  

I only consider fire and water flood an emergency(a snake once too), most items can wait until I call the owner and get an approval anytime there is a repair.

2) Repairs: is the PM charging to much for repairs or doing repairs you do not approve?

. - sourceAnd while the average project approval time for new construction is about four months nationally, it takes eight months on average in L.A.To recap, here are some of the challenges inhibiting development in LA:Getting entitlements for new development is expensive and timelyNIMBYism and the control of local communities over the planning process adds tremendous risk as a project could be stopped due to law suits, lack of approvals, or requirements which make deals unprofitableThe high cost of land and entitlements coupled with a lack of incentives restricts the pool of developers who can afford to developBecause it is so challenging to develop and because we have such a shortage of housing, developers can only make their deals profitable if they target high-end buyers, further contributing to macro-gentriction wherein only the affluent can own homesThat said, it isn't impossible for a developer to develop.

Yes, most lenders can get a loan done in 30 days, but the problem is the title work, etc. that generally occurs After loan approval.  

Once in awhile I get a call to get approval for repairs.  

With the mobile deposit feature on banking apps its so easy to deposit checks.

If you are using a title company to close, which I hope you are, they will send out a mobile notary for closing or coordinate with a local title company for the seller closing.
