Remember people who have nothing to hide embrace.

Are you experienced enough to see if you have termite damage, a rotten sill, un-permitted plumbing/electrical work (homeowner specials), subtle signs of water penetration, or any number of things that will kill your deal on the sale side? 

I recommend embracing math as a good thing and ignoring anything to the contrary.Paying for the first property with cash is good, in that it allows you to refinance to get your money back, however.

Service penetration rates and rankings of importance are almost identical no matter the income range

Fill the cavity with insulation (like Roxul Safe and Sound and be diligent about sealing any penetrations around electrical boxes with sound-deadening putty.

Congrats on your first Rental, I too am looking to penetrate the Idaho Real Estate Investment Market.

IE an apartment.. but for the urban dweller they can rent those for 800 to 1200 a month so a nice income on your exisiting sfr.One of my buddies is contemplating building a developemetn of them in Roseburg Oregon he owns quite a bit of acreage there  and in our state every parcel has zoning period .. so this is a project that has to go through the subdivision map act.but in Oregon they embrace small lots.. ie 1 to 1500 sq ft lots are common.

My first thought is that if you don't want partners then syndication isn't for you until you are embracing the idea.

Yes, I agree with @Steve Rozenberg Don't embrace their responsibility.My aunt used to say, "Don't throw the ball then run over and try to catch it too."

Do you know if it penetrated to the first floor walls and beyond because if it did it will be much higher than just remediating the basement.
