Their appraisals are not only to ensure that the the home is worth at least the amount of the loan, but also for "safety". 

The two times I was patient yielded me much more money than my impatience cost me the third time.

If not, then it is not likely going to be a safety hazard for a tenant or their kid to pull a fuse out and stick their finger in that box. 2.

Be patient.

.)- what alarms (burglar, fire, smoke, CO, etc..) are in place and what other safety features (extinguishers, fire doors, emergency lights, video survelliance, etc.) that are presentThis type of info needs to be gotten from the current owner or property manager and they are more likely to get it for you when you are a potential buyer than after. 

Found through local wholesaler - we overpaid a little but got great terms (he was getting cash offers and was really patient with our first time through the HML process).

Follow safe recommendations, ladder placement, safety rope, how to walk on the roof etc. 

Last, but not least, be patient and don’t get anxious to sell. 

Here are a couple examples that I've worked with.Example 1 - South End of Sewell - BRRR Duplex (2/1 & 2/1)Acquisition and Rehab was $200kARV: $240kIn the deal for $20kRent Roll : $2800 a month(1400 a unit)Mortgage: $1400 a month (200k @ 7 %)Taxes: $516 a monthInsurance: $100 a monthLicences/Sewer/Gas: $20 a monthVac/Capex/Repair: $316 a month (that's a lot but lets be safe)Cash Flow: $448 + you have 40k in equity and a fat safety net each month due to an accrual rate of $316 a monthExample 2 - Lindenwold SFH - BRRR 4/2Acquisition and Rehab was $110kARV: $140kIn the deal for $5kRent Roll : $1700 a monthMortgage: $700 a month (105k @ 7 %)Taxes: $441 a monthInsurance: $90 a monthLicences/Sewer: $15 a monthVac/Capex/Repair: $200 a month (that's a lot but lets be safe)Cash Flow: $254 + you have 35k in equity and a fat safety net each month due to an accrual rate of $200 a monthThe Sewell usually has ideal tenants and very little headaches.

I am curious, have you had any concerns with your personal safety buying mobile home parks?
