If I use the LLC's income to pay the HELOC payment directly, will that pierce the corporate veil? 

And I do agree, the current rate situation and not wanting to put a ton for down payment, I’m not really seeing cash flow… but it’s definitely an area I’m interested in for appreciation and will for sure continue to research further.  

Things were going bad from day one however we wouldn't be aware of it until late 2017.It started when 1 of our properties got burned and when started an insurance claim learned that the policy the management company has purchased for us wasn't covering the cost of property purchase and their savings of $20/month cost us loss of thousands of dollars.That was the start of our awakening and we started checking all that was taking place and we have questioned all the different bills and reports that were provided to us, during that we learned that 2nd of our properties was abounded by the tenant and the months late rent payment wasn't questioned by the management company, not only that but thieves had broken in to steal all appliances and vanities, created damage and leave the property completey vandalized, a squatter had taken over the property and we had to go thru eviction process.Needless to say we have dropped Mousa and his so called management team (Omar and Wanda) and hired another company to take over and conduct a full due diligence on our properties which helped us to find out that on a 3rd property the management company had failed to fill out correct paper work and the tenant was not paying her utility bills for months and that mistake of paper work forced us to settle thousand of dollars past due bills with the city, that's on top of the fact the tenant was way past due on her rent, this property was so badly maintained despite the fact we have paid thousands of dollars to Mousa and his team for various repairs they have reported and invoiced for.As you can imagine the poor management of this company had caused us nothing but losses that are at this point estimated in tens of thousands of dollars.It is clearly our responsibility of not checking this company in details before engaging in business with them, however it is this company lack of responsibility and management that caused our losses.Be aware and check them thoroughly before engaging

Obviously no one has a crystal ball and knows for sure, but since you would be here for a few years, keep in mind the refi process with a VA Loan which is an IRRL, is cheap and simple...so even if you buy now with no money down, use your $15k savings for some value add to the property, and then rates continue to decline, you'll be able to easily refi with a VA IRRL and drop your payment anyways before you go transition to LTR in the next few years.Lots to think about, plenty of ways to go about it, not right or wrong, just depends on your needs so reach out if you'd like any guidance...

Do you have the down payment and closing costs?

Furthermore, you should be getting a cut of the proceeds of the sale (again, GPs will take 10-50% depending on deal structure), so even though cash flow is disappointing, you should make something on the sale, if the GPs manage to get a good sale price. 

After 5 years you will need to refinance or balloon payment.

The 3% interest rate is an important part of this calculation because the principle paydown portion of your payment is significant, I'm going to guess you owe about $300k on your loan which would make it about $7k per year.

Hi.I am looking for a smaller, around $50,000. line of credit to be flexible for down payments, construction cash, and/or just to have in case of unexpected repairs. 

Maybe your bank could offer you a time deposit so you lock in higher rates for the next 18 months if you believe the rate cutting cycle is imminent.
