Given that I've been able to find brokers willing to give me a HELOC off my primary residence with a fixed rate are there any drawbacks of using a HELOC instead of a conventional loan vs a home equity loan? 

Having a hard time finding a lender who lends on 75% of the ARV.

I want to be a full time investor in real state and being an architect really helps in the rehab process How did you find this deal and how did you negotiate it?

Usually has a hard to find list of investment properties coming to the market and ones already approved for STR like VRBO and ARIBNB.You can find him here or Google Anthony "AJ" Wong 

Thanks for the response I should have made myself more clear plan on posting it for sale in FB groups for STR owners and sellers as there seems to be a large of people looking for off and on market properties there hopefully can get lucky and find someone serious.

to get to the point, i would find an area likely to experience more demand and ensure the financials work out for both MTR & LTR's. i would ideally start out with a fourplex and depending how that goes, possibly scale from there. i do believe that it is more traditional to syndicate on larger properties so i am wondering if you know if it is possible to syndicate, starting off, for one fourplex or even one MTR condo. my gut feeling is to start with one beach-front condo in florida that requires $37,250 down . a new construction fourplex, however, i could finance with a USDA loan myself and not have to consider investors so that may make things easier, possibly.no airbnb's. maybe VRBO. two week minimum stay. only in areas very likely to have housing demand due to new factories being built.i own/run an STR right now and it is going well with only the occasional hiccup.

This is the right place to find connections and ideas.

The problem I see is the masses have not understood the advantage of purchasing a duplex.As far a Lennar is considered an entry level builder, I don't see that their neighborhoods in general have very good price appreciation, unless they are in a unique area where the location is exceptional.I think that prices are falling, and that you should be able to find a deal, the I-35 Corridor from  San Antonio to Austin is a very hot area.Here is an example of a property that was listed for $342,000, and the list price is down to $300,000, with a price drop of $20,000 on 7/29. 1261 Stone Rim Loop, Buda, Texas 78610, If you need any comps or info, just let me know, I'm a licensed Broker in Texas, and I have MLS access across the state.Also, I'm not sure if you know, but you can split your 1031 exchange and purchase multiple properties instead of just 1 property. 

How did you find this deal and how did you negotiate it?

Have you looked into Free leads, like Foreclosure sales, Bankruptcy Filings, Divorce Filings, these are all places you can find leads for free by doing a little work yourself.If you want to fix and flip or buy and hold any properties, we can fund up to 90% of the purchase price, and our rental rates start at 5.3%.Hope this helps.
