On the topic of things you'd like to see on the BP Rental Calculator: I'd like the option to enter a percentage number instead of the closing cost amount, to be able to set a desired COC Return percentage and leave the rental income blank (for cases where you don't know what the rent would be but you can see what it would need to be if you set a 12 % expected cash on cash value target as an example), and it would be super cool if the calculator (knowing the location of the analyzed property) could pull in rental comps of like properties within some radius of the target property, and if you could add a box below the property management entry point to add a fixed value for cases where the property management company charges you some or all portion of the first month or some agreed fee to place a tenant, it wouldn't affect your bottom line except it would nice be able to add that to your budget for planning purposes as part of your cash to close calculation.

You might also be able to get blank copies online from the county recorders office that your property is located in.

The download PDF button brings up a PDF with all the fields blank.

So they open the PDF where I've left purchase price, down payment, and date blank, put in the correct numbers, and it's already got my signature at the bottom & I'm ready to vouch when out of the blue a listing agent calls about someone I haven't spoken with in six months that just wrote an offer with "my" preapproval included in it.

It’s coming up blank on my end.

I have ideas on what I want to do, I just need to fill in the blanks with what is available to do this. 

And, of course, the signature on the original document and the signature they taped to a blank form are exactly the same.

What are you going to do when the current fixed term ends and you are staring at higher rates, and the cost associated with multiple refi's over the life of the property.What folks should be looking for is a residential portfolio loan.

I would recommend having a Real Estate attorney draft you a set of contracts with blanks to fill in the variable information that you can use for both sides of the transaction.

Your answer is staring you in the mirror every morning.
