Basically I plan to build a portfolio fairly quickly with an end goal of living off the residual income.

It's good for finishing off the last residual.

What you need to get is an insecticide specifically designed for fleas with a growth inhibitor & residual effect.

I assume you can protect yourself by using meth-residue-detecting kits and doing due-diligence before you buy, but is there any sort of insurance that can offer some level of protection in case one of your tenants decides to go Breaking Bad and cook meth in your rent house after they rent it from you?  

For an example, this is what we recently charged: $185 extra cleaning charge to remove smoke residue off walls, woodwork, cabinets, fixtures.  

Subtitle B, section 1411A: At a minimum, creditors generally must consider eight underwriting factors:(1) current or reasonably expected income or assets(2) current employment status(3) the monthly payment on the covered transaction(4) the monthly payment on any simultaneous loan(5) the monthly payment for mortgage-related obligations(6) current debt obligations, alimony and child support(7) the monthly debt-to-income ratio or residual income and(8) credit history*Creditors must generally use reasonably reliable third-party records to verify the information they use to evaluate the factors.

This type clicks together and is 100% waterproof, no adhesive, easy install over a smooth level sub surface.

We put that in all leases, and if we find cigarette butts (or other types of smoking residue) lying around the premises, we have maintenance take photos, clean it up, and back-charge the cost to the tenant.Of course, in the case of larger multi-family properties where it is more difficult to place blame, one can often find a 'watchful' (read nosey or allergic) neighbor that will happily bust the sneaky inhaler. 

I discovered BiggerPockets a few different ways but primarily through their podcast.I'm a former college athlete, married to an amazing wife and truly blessed more than I deserve to be :-).I currently work in medical devices (Trauma consulting).My wife and I have had success in direct sales and experienced, and still do experience, the power of residual/passive income and are addicted to growing our assets column while we are younger and pre kiddos.

I also placed craigslist "free" ads for items that she left - 24 containers of flooring adhesive, 10 rolls of carpet & padding remnants - and don't plan on charging for my time to deal with the ads and the people.Things I am planning on charging her for are the supplies for a broken ceiling light, 2 missing smoke detectors, missing window screen, ruined screen door, hazmat disposal facility fee, landfill truckload of garbage fee.One of the bedroom doorknobs was in 2 pcs - is this wear and tear on an older house?
