In a mobile home park, most of the value is in the underground infrastructure, roads, landscaping, amenities, pools, fencing, pads, utility pedestals, etc, while only a small portion of the value comes from a building, like a clubhouse or laundry facility.

Down the road, this can hurt the investor because you'll find yourself with a unit rented well below market rent when its time to sell.

For example, I mention that every adult must pay a $30 application fee, pass my credit/criminal background, make a combined income of 3x the rent, and whether or not the property accepts pets.

LOL  If there's going to be problems down the road, their advice or forethought as to the planning/building of the structure, at least the flooring/layering on top of the existing structure, is going to be sooooo vital. 

Turns out it is just a bad time with the current economic environment, I will try again down the road!

If their timeline is further down the road (i.e. 6+ months) ask them how you can be of value to them during this preparation stage in their journey.- Experience.

Over time, gain knowledge and experience so that one day 3 or 4 deals down the road, one is ready to handle the huge responsibility of taking care of other people’s cash.One should also take stock of where they are at - what strength and capabilities they have, what income, what amount of capital, who their social and professional sphere is, etc etc and then come up with a real aka tic plan as to how to proceed.This all can be done but it takes a cold hard assessment of reality and then consistent effort over time to make it happen.Now that @Amir owns some rental property, he can tell his friends, family and associates about it and as they see him do well, NOW he will have more success asking for capital to do bigger deals.There’s an expression How does one eat an elephant?

Regarding purchasing another house down the road....the "new" bank will want to know what is going on with a mortgage showing up on your credit report. 

They may try to buy a house a few years down the road and pay you off.4.

Post Road has a particularly bad reputation.
