@David Ptak - What you're looking for is a combination of the the BRRRR calculator and the flipping calculator to do those computations.  

Right now I am attempting to combine both loans but the borrower's don't have that much money.

Does it have to do with your knowledge, cash on hand, relationships built, or a combination of all the above?

Rarely perfect, even over 10 years.

Or some combination of the three...The second position lien bit is a function of the reality that if another entity participates in the financing package, he/she/it is unlikely to accept anything other than first position lien, which pushes the owner into 2nd.The only other option (and I say that with a laugh since there are only about a billion  options) is either bridge financing, unsecured financing, cross-collateral with or without blanket notes, etc.

She works opposite shift of me so we rarely cross paths, but she's always been responsive to email in the past.

Based on my reading at BP, for a 1031 Exchange, I know that I have to purchase a Replacement Property for at least $340K and I have to put all the proceeds $170K into a replacement property purchase to defer tax.Question #3: If I can provide additional $30K to combine with the $170K (a total of $200K), does this mean that I can only afford to purchase a Replacement Property between  $800K (with 25% down) and $1M (with 20% down)?

First off, good deals are made, rarely found. 

Sometimes it's in your best interest to have someone on site but it's pretty rare..

And if you have decent credit already, combine that with your "projected income" and bam you can qualify.
