They are my problem child so to speak... they fight often, slow pay and keep the yard a mess....

They Key is to first have a good team on the ground you can trust, and know that they are capable and have experience in Rehabbing properties to good standard. 

I’d fight tooth and nail also.

If your time is worth more doing something else, then hire it out.If you have someone you can trust to do a good job.....just as good or better than you....hire it outIf you like to be involved and be hands on, then do it ....up to a point.I prefer to do everything I'm capable of myself....if I have the open time.

You have the capability to evaluate this decision.I purchased one fully rented property in September and have another under contract that is half rented.

We raise rent to 50% of the gap between current rent and market rent, to make progress but still reward long term tenants.Long term problem free tenants are good, but tenants who so flagrantly break your rules and disrupt the quiet enjoyment of neighbors are not worth fighting for.

Now the amount of properties available are slim, but not sure how ready they are going to be to fight/prosecute you... for having a discounted rent option for "Good Neighbors Next Door"Good Luck on whatever you do!

If there isn't a set space for each tenant's dog, make sure you require renters to have insurance-- dogs fight, and vet bills are very expensive, and they will be quick to involve the rich landlord and somehow try and make it your fault.Lastly.... how the dog acts is  99% reflective of  the owner, we have one duplex unit, she has 4 dogs, takes A+ care of them, walks them, lets them out.. 0 damage to the unit.. so it's really all about the owner!  

If it is the only way that you would qualify for a loan then go for it however make sure that you will have the capability of refinancing after a year 

If you and your agent think your right just don't sign the release.. the buyer for sure is not going to sign the release to you.. so its just a stalemate..the title company will hold the funds until such time as they interplead it to the court .. then you both hire attornies.. and fight it out.but in the meantime most folks would come up with a win win for this and split the money in some fashion ( assuming your correct that this buyer was out of contract and defaulted)
