I've seen missing support beams, various issues that builders said they would resolve / never did up until closing, etc.

The biggest issue that you are going to run into here is that the home was vacant. 

I've had 2 issues with tenants not paying rent resulting in them leaving and yes they left a mess, but we cleaned it up, got it re-rented (for a lot more money as there are rent caps in place in that area) and moved on.My first rental was accidental-I bought it to live in and moved and converted it into a rental. 

Mostly this hasn’t been an issue, more often than not since I work 3rd shift I end up having to call my handyman about something between 6-7:30am prior to getting off work at 8:00am.

In that case, if the owner is sued he will have that ‘army of lawyers’ working for him, not against him.

Luckily for us the issue was not huge, but we missed the inspection window before we found that out. 203(K)’s have higher rates than standard loans, so consider the timing of your refinance (especially in todays environment).

*This question is for any property manager or people with prior property management experience*What would you say are the biggest issues that reoccur when dealing with tenants, vendors, etc?

I am wondering if anyone has dealt with similar issue before?

Heavy rehabs or rehabs that are bigger than the purchase cost range from not allowed to case by case to no issues, so all over the board on that issue.

Does everyone think this is true, are all buildings going to have issues with them, and I am not referring to cosmetic ones?
