The LLC is a pass through entity and will show up on your personal Schedule E and once the property shows up on the LLC, the debt (that probably won't show on your personal credit report) will be included in your total debt. 

@Michelle Fenn  We had properties listed for sale, posted on local MLS, propagated to Realtor and maybe 100 other websites including zillow, trulia etc. 

However, my take on this is they did not do sufficient due diligence on many fronts, including city government challenges, operating challenges, infrastructure challenges and marketing challenges. 

Coffee stains under the fridge or a dust bunny in a corner, not if you want the 5 star review and the repeat bidness 🤪 What would be included in a deep clean that is not normally cleaned?

If you were able to pull out $500,000 in existing equity out of a paid off rental and disperse those funds to acquire 2, 4-unit MFR properties and had the income to support any future CapEx and the interest payments on your HELOC ( including the extra income to paydown the loan ) would there be any " gaps " or problems I'm missing in this situation where it would be a bad enough idea to not go through with acquiring more properties through a HELOC on 1 of 5 properties you own?

Is there any evidence or support I can include to make my letter of intent more credible?

The Condominium is high rise new building w/ high service luxury amenities including concierge services, valet parking etc.

And yes we get a deal when we contract for 90 house plans we pay 2100.00 per plan and that include engineering.

Are the scanning/mail forwarding/etc perks including in the pricing? 

I don't understand how you can't track them down.You could stop paying HOA dues, and that will force them to contact you.As for the PM, I would instruct them to hold off on painting until the termite issue is resolved, which includes providing you with contact information of the HOA board.
