My team has conversations all the time with borrowers, especially those that own real estate, that  thing DSCR options are their ONLY options.

If you need a conntection in Upstate NY I can direct you to the right person.

I am aware of products once I own the property, but what about lines of credit to secure a winning bid? 

It has become and really continues to be my "one thing" on a daily basis.When you couple these forums with the other opportunities like BPCon, you get invaluable experiences, just like being in a room with 15 other people getting some personal help with your profile from the one and only @Scott Trench.  

I have one property my wife owns, and soon we will have two.

I have a Client that I am currently working with who owns a 2 unit commercial building in St louis Mo and he is looking to sell it cash or seller financing with the right terms .

@Devin James  I'm straying from the question slightly, but personally if I was able to raise those funds, I would use it as a downpayment and get a loan for the rest. 

A big reason is the OO requirement to rent the JADU as its own unit,good luck

One thing to note when getting conventional mortgages and spouses.There is a 10 limit per person for conventional financing.You can either do 10 conventional in each person's name which would be 20 mortgages for 2 people or if you do the mortgages jointly, will only allow 10 in total.My thoughts are not to own joint assets until you are both married. 

I can provide support of checking in on contractors, staging rental properties, walk potential leads to give you an idea of the property in person or what the area is like, meeting with agents, and drafting scope of work for projects.
