Which is much more workable for this deal, but leaves me wondering where that first number came from.

@Danilo Ojeda glad to see we are on same page, that is the foundational point as without that none of the other things I am going to say will matter, it's gotta be a foundation that is workable. 

The complex has an HOA in place, numbers are workable (would like to get the price down some-have Not made an offer). 

if you know your numbers and are willing to walk if you don't get them then you will be fine.It can be a workable strategy for sure.

IF it's going to be simple to get the permits for it, it complies with relevant zoning (otherwise the permitting will be much rougher), and if people will pay to lease it and it doesn't hurt the cashflow of your other two units then it's a workable deal. 

It sounds like there are realtors involved so they should be able to sell the need for the seller to be workable.

Sounds like a workable approach.

A slight inconvenience, but workable.2) You would have to work with a second bank to obtain a loan for your new home, and accept a commercial loan, putting 20%-25% downpayment instead of the lower downpayment primary loans qualify for.or) You could explore owner-financing or private money.3) You would have to double up on insurance to be safe for the first year, because you'd want a second policy as a landlord since a homeowners would not cover renters.

(Not really workable as I am Looking to house hack in North Dallas where my business is) I thought I should look for private money and wondering who could (or would) use cash flow of the property as part of my income?
