I hope you will be seeing lots more of me in the future.

Help them tie their decisions to their costs or future increases.- If costs are high, send out a letter saying you noticed a spike and that you will be scheduling an inspection to look for issues with the property, like leaks. 

What should I do with a potential tenant buyer who says he has up to $50k to put down on a property but he has very little credit so he probably can't qualify for a mortgage in the near future? 

Since it takes so much to take the papers and start running my apartments I consider now starting a business where I can deduct all my expenses like the homes fixing at the beginning and the future properties that I consider buying but by doing this plus the short-term renting that I consider with tourists/visitors I feel more risk exposed since I will have to pay for a business loan with 6% interest, and an accountant to keep my business papers which will need another 120€ Monthly(that's for a Private Company which is considered to give a legal protections since me as an Individual is not exposed similar to protection that an LLC provides at the USA.)What is the community's opinion about what will be better for me? 

When you market a home with a particular amenity, you have a moral obligation to ensure that amenity is maintained. it doesn't matter if you told them the tub worked or not; they saw it and assumed it works so you should ensure the home matches what was presented.If you don't intend to maintain the tub, be sure to disclose that to future renters.

I know now that wasn’t a great move and will do things differently in the future 

I felt like it was, however, a defining moment for my future real estate career as I can now spend even more time reading and networking.

I think it can hurt in the future, if I don't disclose everything.

I would think, on the other hand, those effected properties will have a signification price / value drop so you might be able to get some from those who just don't want to deal with that or just walk away.I'm a long term investor (10+ years) so i would worry about global warming, sea level rising, stronger storms and more flooding so i would probably avoid areas that was historically effected or might be effected in the near future.

Hi BP, I am only 16 years old and I plan on becoming a real estate agent/investor in the future.
