@Nicholas CookIn indiana there are no laws that allow a tenant to withhold rent, or rent concessions based on how fast a repair was made.If the tenant believes and can prove the house is not habitable or some issue that needs to be addressed, they can move out breaking the lease, and not be held liable for doing so.Beyond the law, if this was a situation that got drawn out weeks, I could see some compensation being appropriate.

Information About the Property and Comparable Properties in the Area are VITAL!

I always had to earn it and I believe that really inspired my competitive nature and frugal spending habits.

However, I haven't been paying attention to how I could go about building the interpersonal relationships that I have lately heard are so vital to success.

$30k houses can be a lot of work especially if they are habitable when you are purchasing them for $30k.

They are acting as an agent without the laws, ethics requirements, education, and insurance that are vital IMO.

Should I have not listed the state I am sure I can still prove vital in the consulting side of things.I recently purchased a property where the claim was at around $3,200.

@Michael Bangsal, cash flow is vital but you need stay focused on your cash on cash return.

If you are looking to liability then none but with the right insurance and provided you are adhering to landlord tenant law by owning and operating safe habitable dwellings, you are in good place.
