Look up the BRRRR strategy if you aren't already familiar.

The 11 units are the maximum possible on the propertythe tenants have always paid their own utilitiesThe units are all city water and sewerRegular upkeep is that the park occasionally gets new gravels and someone is in place to cut the grass for $75 every 2 weeks and I pay for two street lampsThe property taxes in 2018 were $900The property without the 11 units appraised at $110,000 The trailers themselves aren’t worth a great deal of money I’m sure but the way I’m looking at it I’m buying the whole park is basically buying myself income I expect after taxes and expenses to net at least $2000 a month, does this sound like a winning project?

It is certainly important, but if proper systems aren't put in place then the business suffers.

And I can't believe I can't say I have the tax lien and am about to foreclose and would rather pay them then the courts if they aren't going to redeem and want to quit title.  

I will look it up to confirm.As for the gift letter, they are required, but that does not mean they aren't sometimes overlooked by inexperienced/unfamiliar loan brokers until the file has reached underwriting.

People in real estate who have so much leverage that they would lose 50% of their holdings aren't investing they are speculating.

If you plan on moving into the property, you might be able to do the owner occupy 3.5% down FHA loan, or if you aren't planning on moving in, most of the times it is 25% down with a conventional loan if you go that route. 

Do some have extendable time periods so they aren't forced to sell at low prices? 

Comps are tough as it is the smallest (1/1, 800 sq ft), worst looking/condition house in the area & we aren't in a neighborhood.  

I recommend the podcasts if you aren't already partaking.
