I'm looking for Propstream, does it have different post cards, like deal machine???

Of course credit card is going to be like 3.5% but it does kind of such because it's already hard to get tenants to pay it lol. 

Is it true that marketing and advertising to find motivated sellers could be thousands of dollars a month?

None of that is true. 

I would try not to tie up any of the principal in down payments.Personally, I had a family member do this same thing, but they used an investment portfolio as the collateral instead of real estate.If you play your cards right, this might be the only short-term money you ever need.Please let us know what you end up doing.

However, I noticed that as a Costco member, they also offer HVAC services, including the same product line (Lennox), along with a 10% Costco Shop Card if you go through them.Has anyone here used Costco for their HVAC needs?

This has been my strategy here in NOVA as well - though true multifamily housing stock is hard to come by as you are probably already aware.

When I think about this, I don't see many downsides, so it seems a little too good to be true.

That's SO true, isn't it?

I have two banks that have done so as well as a credit card, and know of a couple of organizations that have as well.
