I sent my normal residential lease agreement to my attorney and he modified it to implement the following:1.

If you accept, the entity that you are requesting information from has 30 days to comply and fulfill your request from the date all monies are paid and you have answered any/all questions they have about your request.If they deny your request, you are more than welcome to submit a modified request.

And the leads you can't get in touch with updates info every 36 hrs.also has contracts you can modify.

Roof costs say $8000 (depending on size, shape, type of shingles, etc.) and last 25 years (depending on weather, type of shingles, slope, etc.) ... that's $27/mo you need to put away in CapEx to eventually replace the roof ... now do that for all the systems in the property, add them all up, add some reasonable amount of margin, and you have a reasonable grass roots estimate of what your CapEx should be ... code it into excel with the approriate parameters such as square footage, number of water heaters, etc. and you can knock out a CapEx estimate for a specific property in a matter of minutes, without messing around with bogus rules of thumb like 50% rule or 10% of gross rent, or any other such thing that tries to relate things that are completely unrelated in order to shortcut around actual thought and analysis.Any calculator that you do not understand all of the inputs, outputs and assumptions that went into them are less than useless, and BPs are no exception ... therefore the best ones will be the ones you build yourself from the ground up and modify over time as you gain experience and find that some of your assumptions, inputs, and formulas need tweaking.  

They can generally be called by the bank or modified at will.  

There were other reasons for me to walk...all involved me getting the return on time and money I require, but, and this should be stressed, it's a Federal program and could have been modified to your benefit since I examined it. 

Sounds like I need to modify my listing.

If yes, then you have to abide by the contract the seller signed with their real estate agent or get them to modify the contract.While the Seller may have to "abide by the contract...signed with their RE agent", in terms of paying or not paying a commission, the rest of the terms that might be shown on MLS (or within the actual Listing Agreement) have no bearing on a Buyer's Offer to Purchase.

At the very least you will want to modify any existing bathrooms to make sure they are accessible and have walk-in showers.

In fact, I lost a deal last year because it took me too long to modify hundreds of lines of pricing every time there was a Change Order, whether from my hard money investor or my contractor.
