I'll skip an avoidable one like this.

The RPOA also does a once per month happy hour at Harmony Hall and a Friday morning breakfast every week.

Are there cost effective ways to deal with this like just putting new siding on or is it so dangerous that I should skip it all together and look elsewhere?

In San Bernardino county for example they will have probably 500-1000 time shares that are all the same starting bid that you can just skip over. 

Once you have the names, a simple skip tracing service such as Enformion or TloXP will get you numbers pretty fast. 

If you know of all the restrictions then just skip to section 3. 

The fact that they skipped out on rent, is a different story.

If you instead got the bank to agree to finance the repairs, they would list 100K in budgeted repairs on the HUD statement (closing statement) and then you would put down 20% of 600K (the all in price) and get a mortgage for 480K (you put up 120K) they would then hold the extra 100K in escrow and release it to you as you made the repairs.Techincally this is different than BRRRR since you are really just buying, rehabbing renting and repeating ie BRRR but are skipping the final R (refinance)

I would skip on this guy and keep looking for a tenant without an eviction history! 

Be sure and keep posting here looking to connect and the best way to do it is to offer to buy coffee, breakfast, maybe lunch, dinner or a beer.
