What you have to understand is if your park is legal , legal non confirming , or illegal .  

Wholesaling takes dogged pursuit of non-competition deals in order to be able to buy at the deep discounts.I highly recommend wholesaling but, as @Jay Hinrichs and @Jose Castillo mentioned above, it's not an easy strategy to get into so don't get discouraged and don't get stopped!

Id expect 5.5% to 6% for non owner occupied mult right now.

I bough a bank owned ( non- auction)  property and instead of eviction I offer them some money, they were out rather quick. 

Additionally, they have restarted the public water/sewer expansion project and will have most of the city on pubic utility within the next 10 years.

Non payment is justification for eviction.

It has public sewer and water.Should I do a sewer scope inspection?

Should be a non-issue. 

I explained my other refi inquiries for all those years and asked her how could she do it....she said, they were all wrong because I had a VA loan on it, the non-owner occupy rule did not apply. 

Stay in your lane and worry about you and DEFINITELY don't go on rants in public using poor grammar and profanities.
