As I grow older (25 hahaha) I am becoming more frugal and more careful with my money.

To be honest, the dog issue doesn't deter me too much.

Then my wife's sister agree to take care of her for another few months.

Plus whether to allow dogs.

Once the house is sold, the lien will be taken care of and the seller will walk away with a profit. 

Take care of the deferred maintenance then raise the rent to just below market rent if tenant is a desired tenant, to market if tenant is so-so, to above market if tenant is below average.

It is not taken care of at all, great colonial, and it's in the middle of my towns main street/downtown area surrounded by great houses. 

Offer accepted on my first deal (triplex) and inspection pending (WA State).During my initial walk-through, I met a couple who seemed to be more than knowledgeable about the property, possessed keys to storage areas (possibly other units too), had special parking spaces, and stated that they take care of the things around the place including the large yard in exchange for lower rent.

While you might not care about exactly what kinds of soil you have on the site, the most important thing is the water table, especially if you're planning to build a basement.

Ps be careful who contacts you because of your post.
