I would ask you to remember this for those times -- whenever you choose to do a tenant in distress a favor or cut them a break, always ask yourself if you're really helping someone or just enabling their self-destructive behavior.2.

You won’t know what offers you would have but don’t receive because of this behavior.

Although they were not at all abrasive during the purchase, we have decided to keep a close eye on their behavior as tenants.

However, you could start by helping an investor "bird dog" deals for a finder's fee.

That being said, if there are dogs in there that you and he agree would be better off gone then you're going to have to look to 1031 exchanges to avoid a horrendous tax hit that your grandfather has been avoiding for decades. 

They currently rent out a 1 bed 1 bath unit with 5 small dogs.  

@Nadine Delille So here are the options for low cash investors (just a few)Wholesaling off the MLS: need to double close more than likelyWholesaling: find your own deals via marketingBird dogging:  Might get money for any lead you find with your own marketing and turning it over to someone thats more experienced.Lease Options (alot of stuff here but lets simplify it:  you become a middle men for hooking up a landlord and tenant)Flipping houses: if you have PML and HML who are willing to pay for everything but for a newbie will be extremely expensive on your end profit (plus if you need to pay points for the loan)yeah many agents are investor friendly meaning that they will go with you and see houses write up offers etc but when it comes to wholesaling off the MLS what you need to do is the double close.

If they need bird dogs then be a bird dog.

Where that dog did this thing..OK fine fineYou start.... by...just doing!

How about helping someone bird dog for properties?
