Just a quick note for your question, HELOC is taking a percentage of the property LTR around 70% for best rate and up to 80% probably for a higher rate, then subtract your outstanding balance on the mortgage.

It will rent for around 3500-4000.Two month later, the listing agent called me and said the damn house sold for 1.2 million, and wants to list my house.I do not know who bought this sucker.

As others have said, they are outstanding.  

My view is the last 10 years have had outstanding appreciation that likely will not be matched going forward.  

I get it, owning an apartment building is exciting, the value add possibilities are outstanding if purchased correctly and the cash flow can be life changing.However after 15+ years of investing and owner of small apartment buildings I can tell you the excitement is getting a little a head of itself. 

(No you  are not asking a dumb question, it is probably me as I am one of those damn foreigners) ha.What do you mean with "this"?

(Proof of constant full coverage insurance needed and get repossessed for non-payment)   Not an appreciating asset, but if you can get a nice one to cash flow or buy the whole damned park why not?   

The Fannie standard is 6 months PITI on subject investment property, and 2-6% of outstanding balances on all other investment properties.

The other financed properties reserves amount must be determined by applying a specific percentage to the aggregate of the outstanding "unpaid principal balance" (UPB) for mortgages and HELOCs on these other financed properties.

I used to have a crew, a damn good one😵yeah 30yrs ago🥴 So?
