Out of those sales you pay for product, overhead and split with the company building the store - they estimate profits of a couple thousand in a few months, around $5 to $7 in about 6 months to a year and more than that if you can built up higher credit.Names around the Amazon Store is Ben Fredricks (the guy from Noteworthy)Names around the Walmart Store is Mark Evens DM where the DM stands for deal maker.Any input around doing my homework on this type of investment or these particular companies would be highly appreciated.

Say you put $3500 down on a home for ~$120k how can I estimate the cash I need to keep in reserves for repairs?

No equity to compare.Cash outlay to hold is estimated at $40k. 

When you get a payment estimate for the hard money that should tell you if the deal is a fit for your cash position or lack thereof.

With the property losing money at that occupancy - which could be normal for the park, I don't think the benefit outweighs the risk - at best you're only bringing in another $5600/mo but with my estimates on RV parks, your expenses will eat that up pretty quick.  

In additon to that, non local lenders often don’t know that Philly transfer tax is 2.14% so their loan estimates are often incorrect.

Save a portion for estimated taxes and roll what's left into the next property.Don't let the tax tail wag the dog when you're just starting out. 

I’d like to learn some basics as we get into the landlord’s game but I think we’d defined be hiring this out, so shopping around and comparing estimates will probably be our next move.

Utilities (e.g. water, electricity): is $300 / month a reasonable estimate? 

Roofer & 1 GC already recommended re-doing, both with similar estimates of 20K for an 900 SF flat roof.- Main beam twisted and loly columns - bones of the house and that worries me- Back wood stairs that lead to backyard from 2nd floor are not properly attached to houseSo far Im bringing (2) more GC to provide estimates for repair of 3 items above and then go back to negotiate with sellers in this crazy sellers market :S.After this intro I wanna ask the community if you have any experience negotiating with issues above?
