For instance, changing the battery in a garage remote and reprogramming it.

last house I closed for instance we put a Jacuzzi tub in so you need a door to get to the motor we left a note on the stud and sure enough sheet rockers rocked right over it.. buyer comes in and thinks we dont know what we are doing LOL..

What you pay with labor will depend on if for instance one of my units still has a good pad and tack and strip then I just pay for carpet and installation cost.What you will pay will also depend on how much you are installing at one time.I don't like Berber for rentals.The design of the loop once it starts unraveling it can unwind pretty good an dis harder to get certain stains and pet stuff out of it.With carpet you want a Nylon carpet even if the cheaper version.Some carpet guys will try to sell you the rubber composite carpet stuff which is the really cheap stuff so it will stand up to tenant abuse.The problem is it can only be cleaned usually up to one time and then you need to replace it again.So I would rather get a cheaper nylon that can be re-cleaned many times over after installation for an additional .10 to .15 a sq ft extra than the super cheap stuff I will have to replace again.If you get 1 sq ft for carpet,pad,tack and strip,and labor install and it is Nylon you are getting one heck of a deal.Even at a carpet place usually you are at .40 to .50 for the pad and .50 to .60 for a cheap carpet.Then you have to do material to install and labor.I have seen sometimes if you have to do a small area you can pick up quality remnant pieces for real cheap and hit that type of number or buy in bulk.

Every instance is different, it's per instance.

For stock investments for instance, just invest directly.

It is our best interest to help support the investor to be successful -- we are not here to sell 1 deal and be done, actually in many instances we've helped newbie investors become full-timers.  

I say that because you may have different inspectors calling out different items at each inspection for instance you may do a rough electrical inspection with one inspector and do a final with a different inspector that see's things a little differently forcing you to redo work already inspected.

It may require you to maintain a specific liquidity ratio over the life of the loan, or maintain cash reserves equal to a specific number of payments, or upon inspection prior to the loan being Funded, Require you to come out of pocket with cash, for instance, to replace the roof because it has more than two layers on it, replace or grind concrete that has heaved, or embark on a program of replacing balconies that have rotted within a certain amount of time, et cetera...

For instance, say I run across a 3 family at 4,000 square feet but its marketed as a 6 bed 3 bath property.

In both instances you want to do your due diligence on anyone you give money too2.
