So, coming back to the trap I mentioned in point 1 above, if I were those people, instead of providing content that's already available everywhere, I would focus on being the best possible real estate agent and then shamelessly advertise my services.

You didn’t mention the property or deal specifics, but for many deals in the recent years, there have been amazing and unusual gains due to multiple unnatural circumstances.

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.

As @Benjamin Aaker mentioned, a personal loan might be a better option.

That 4 I mentioned was bought 5 years ago.

As Jonathan mentioned it can be done, but they may require an appraisal of the property. 

The factors you mentioned are very important to keep in mind for any investment, but I like investing in areas I know. 

What I would do is talk to the neighbor and mention that the fence looks like crap and I am willing to replace it on my dime .

Quote from @Paloma Wodehouse: You only mention two problems.

Let them know how much you enjoy living in the home and mention that you’re planning to buy your own property in 2025.
