I'm not interested in IDX or MLS, but I do want to showcase my listings online via my website.

They had an ATM fund that looked interesting, but I couldn't find anyone talking about them online. 

what it sounds like you are asking is illegal in many ways, section 8 laws, local laws, duel contract laws that conflict, there always has been also those out there looking to catch you breaking them,  avoid it, dont offer it, dont entertain it, there is leeway up if the tenant meets certain conditions, say need 1 floor rental, if not rent may be inflated over realistic market, which is what rented at not listed at, keeping in mind sec 8 market rents also include utilities paid, you can usually reach by email fastest, they have set chart, heat type, neighborhood etc, more than listings found online

And my portfolio has increased 2.5x since purchase.You aren't going to find the next hot area by looking online.

What many may want to consider is how do they scale it.. because as stated 50K profit deals although talked about a bunch on line are not that common at the 200k ARV and under price point.. in these deals I do and see 20 to 30k is the norm..

Many of the good tax sale properties are getting bid up online. 

I'm just cautioning you against taking any specific advice from any other online response.

Pocket listings almost seemed the norm for any good deal, and people online said you had to schmooze and build a relationship with a commercial broker to have a chance of finding the best deals.  

There are templates online, but I am wary of them for many reasons. 

Should I try local CU or any of the larger banks such as BoA that are offering no-fee helocs online?
